Questions related to Terrestrial
I think that ectoin enzyme is important for the soil and terrestrial plant ecosystem. I think that the origin of this enzyme, which increases the resistance of plants to drought, should be discussed. Thank you for your ideas and comments that will contribute to this issue.

With the assumption that the ERA5-Land variables (https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-land-monthly-means?tab=overview) are inputs and outputs of a model (I don't know if that assumption is correct), I am trying to calculate a mass balance for a grid point using the Terrestrial Water Storage equation (TWS; eq 12 of 10.1175/2008JHM1068.1)
dTWS/dt = P + E + R
where P, E, and R are precipitation, evapotranspiration, and runoff, respectively, on a monthly time scale.
Will this point of view be ok, to obtain a water balance on a single grid point of ERA5-Land?
Note: For TWS add "Volumetric soil water layer 1, 2, 3 and 4"; for P use "Total Precipitation"; for E use "Total Evaporation"; and for R use "Runoff", but I haven't been able to get a water balance so far for a single grid point.
I am looking for a reference that compares primary production across different ecosystems (marine vs terrestrial vs freshwaters). Especially, including streams (maybe even headwaters my research focus). I did a quick research and I cannot find anything answering my question within one study. Does someone has something in mind for me?
I'm trying to pass through characterization into normalization for a product which I found on literatture in an excel sheet.
The method I'm using is IMPACT 2002+.
I considered putting my impact categories as follows:
- Human health: human toxicity + respiratory effects + ionizing radiation + ozone layer depletion + photochemical oxidation
- Ecosystem quality: Aquatic ecotoxicity + terrestrial ecotoxicity + Terrestrial Acid/nutria + land occupation + aquatic acidification + aquatic eutrophication
- Climate change: global warming
- Resources : Nonrenewable resources + mineral resources
However, this calculation is incorrect according to the prior example, which was created entirely in SimaPro. I believe there are several factors that are missing.
Anyone could help me ?
How to accurately calculate the terrestrial carbon sink at large and small watershed scales? Model stimulation or field work?
Dissolution process of terrestrial sediments, for identifying major and trace elements, with AlF3 insoluble substance formation.
- How to dissolve these samples？
- Are the AlF3 formation because of samples are too high in aluminum?
Thanks for your answer!
My previous process is:
- 50mg sample powder dissolved in 1.5ml HF, heat at 120℃, close to dry
- followed by 1 ml HNO3 and 1.5 ml HF mixture, airtight heating 72 hours, 190℃
- add 1 ml HNO3, heat at 120℃, close to dry, twice
- add 1.5 ml HNO3 and 2 ml H2O, airtight heating 12 hours, 120℃
Dear researchgate freiends,
I'm doing research for my PhD study regarding rain attenuation for mm-wave based on raindrop size distribution (DSD) in tropical country. Main focus is for terrestrial link and with path length less than 1km. I will considered canting angle as well. Do you think there is any other way to make this research more interesting?
and do you have any suggestions any research that use canting angle as one of the parameter considered in the rain DSD measurement. I found some but it is very few. Maybe some of my friends here have any information that I do not know.
Tq in advance
Perhaps there are databases on the internet. Animal carcasses are an important component of terrestrial ecosystems. I want to make an overview of the confinement to the corpses of a certain taxonomic affiliation of insect necrophages. I will be glad to discuss methodological approaches to solving this issue. If you are interested, write I will be glad to cooperate.
Hello everyone. I am curious whether it is possible to grow terrestrial orchids hydroponically under normal conditions, not sterile. Does anyone have such knowledge? I would wonder if Calanthe could be cultured that way after seed germination in sterile conditions. With a small scale culture system, hopefully we may be able to avoid plant viruses and promote growth.
Dear everyone. In addition to my own primary field of research, I am also engaged in research on germination of poorly germinating terrestrial orchids and their breeding as a hobby in life.I have been currently looking for seeds of Calanthe plantaginea in particular for many years. This species is growing wild in northern India, Nepal and Bhutan. If it is possible to obtain these seeds, I would appreciate any information on how to obtain them. I appreciate it.
Hi there! I am interested in understanding (or making myself more confused, whatever) the evolutionary pathways of coprophilic habit in dung-inhabiting fungi. Taking into account the dung of herbivore animals as a substrate to dung fungi growth, we have few "candidates" to be dung-producers with some requirements to early dung fungi (e.g. the amphibians Ichthyostega (I don't know if it was an herbivore or omnivorous, appearing about ca. 375 million y/a in Devonian, once the first tetrapod herbivores made their first appearance in the fossil record near the Permio-Carboniferous boundary, ca. 300 million y/a.). Terrestrial plants made their first appearance ca. 450 million y/a, with a well-accepted role of arbuscular mycorrhizal fungi in this process. So, my question is about if there is some study dealing with the evolutive process of dung-inhabiting fungi, presenting some consideration where and how, in the evolutive process, this ecologic habit firstly appears? Any considerations are welcome! Thank you!
If you want to help me with this question with more details (or more questions ¯\_(ツ)_/¯ ) or papers/books, feel free to also send me an email at: firstname.lastname@example.org.
If this is so, then we must credit this change to global public awareness and activism against the rampant pollution, degradation and the destruction of the global environment and the mental health of our young generation; caused by consumerism and the insatiable profit-making schemes of monopoly capitalism. It is to the credit of the brave teenagers like Greta Thunberg who inspired and mobilized the world youth to environmental activism and more recently by the profound soul of a data scientist like Frances Haugen; who risked her career and probably her life to expose the greed of corporations that knowingly put profit over the well-being of humanity!
This activism of our fresh and young generation stands in sharp contrast to the conformed, cautious and career minded troops of “scientist-serfs” (a term coined by the Bengali poet Tagore) who willingly enable the rampage of the Frankenstein Monster, commonly known as corporate capitalism. Can we now have hope that the activism of our youth world-wide, will form a Tsunami that will drown the Frankenstein Monster forever and usher in a new dawn?
The prestigious Nobel Award is a yearly ritual that sets the direction and the priorities of scientific research on a global scale. For about a century since Einstein’s theory of general relativity, this Award was mainly and obsessively focused on the esoteric theories of physics and on mysticism about cosmology; that served the interest of the established order and theology; but which has no or little relevance to life in terrestrial Nature. Was this a century-long ploy by the compliant Nobel Committee to divert attention from the ravages being done to mother earth and her children by greedy corporate capitalism?
I have been reading and searching information about why insects evolved from being hemi-metabolist to holometabolist.
It has been pointed out that insects have evolved to complete metamorphosis to avoid competing resources between adults and young instars as it happens with some terrestrial hemimetabolist insects. But I am not quite sure about aquatic insects like mayflies, dragonflies, damselflies among other groups. As adults emerged occupied another environment, while some occupied both.
Are there some information, literature about ecological perspective of how these two holo and hemimetabolist insects evolved?.
I am interested in this topic because I want an organism that consumes food waste at a high rate and the data for insects and worms seem more homogeneous. I have to admit that terrestrial isopods have me completely surprised. Some species reproduce at much higher rates than other invertebrates. However, the data in the literature speak of very low daily intakes of less than one mg per g of live weight. On the other hand, as they live at overcrowding levels of tens of thousands per square meter they could compensate this low feeding rate. Even so, it is not clear to me. The species that I keep in the laboratory as a companion to the terrariums is Porcellio laevis. I don't know if I have minimized the effect of terrestrial isopods as detritivores. I know that isopods crush the food considerably and help the bacterial processes of decomposition. I do not care whether they degrade directly or indirectly. I want to know their exact contribution and I repeat, the results are very disparate and confusing. For example in these papers:
Effects of Terrestrial Isopods on the Decomposition of Woodland Leaf Litter Author(s): M. Hassall, J. G. Turner and M. R. W. Rands Source: Oecologia , 1987, Vol. 72, No. 4 (1987), pp. 597-604.
Abd El-Wakeil, Khaleid. (2015). Effects of terrestrial isopods (Crustacea: Oniscidea) on leaf litter decomposition processes. The Journal of Basic & Applied Zoology. 69. 10.1016/j.jobaz.2015.05.002.
These studies report composting rates of more than 70% of the biomass ingested (~millipedes), which is logical if we look at their diet. But the most surprising thing is that they also talk about feeding conversion ratios (FCR) between 1.5 to 2, which would place them at the same level as the tenebrionidae. I would like to set up a discussion on isopods can be used on an industrial scale to firstly degrade waste and secondly to compost. The thousands of isopods I have in my lab inside terrariums don't seem to be effective enough to attract attention. Judging by their numbers the breeding conditions are appropriate. In short: I don't know what to think of isopods. I guess I'll have to do a lot of tests before I decide.

So far, most of methods about inferring the trophic or ecological interactions take account of the circumstance of aquatic ecosystem. Many methods have emerged, such as the method based on body size (Gravel and Poisot et al., 2013) and the method based on published data (Gray and Figueroa et al., 2015). However, these methods have many limitations when applied to terrestrial ecosystems. Are there any generic methods to infer the trophic interactions in terrestrial ecosystems?
Any helpful answers would be appreciated!

Alternative method of comparing satellite and terrestrial rainfall data. So far, I have made a comparison by climate zone, elevation range, location, and years; any other suggestions are welcome ?
We are going to do an RNA-seq analysis to study transcriptomes\ profile of different organs in terrestrial orchid species within genera including Dactylorhiza, Ophrys, Himantoglossum, and Orchis but their underground fleshy tubers contain high content of glucomannan (a carbohydrate which gives special rheological features to products obtained from Salep) and it's difficult to obtain a pure RNA in presence of such contaminations. Is there any special and home-developed protocol to extract a pure RNA sample suitable for RNA-seq analysis from such tissues?
It is known that the pedosphere is one of the largest reservoirs of organic matter on the planet (up to 2060 ± 215 Pg C). This is significantly more than combined in the atmosphere (~ 800 Pg C) and terrestrial vegetation (~ 500 Pg C). It is also estimated that over 12,000 years of agricultural use, soils have lost an average of 133 Pg (petagrams, 1015 g) C, and the rate of losses has increased significantly over the past 200 years. On the other hand, soil microorganisms respond to rising ambient temperatures by enhanced decomposition of organic matter. Can CO2 emissions from the pedosphere significantly affect the increase in CO2 concentration in the atmosphere and, accordingly, increase its global temperature.
Net zero refers to a state in which the greenhouse gases going into the atmosphere are balanced by removal out of the atmosphere. A growing number of countries, cities and companies are aiming for 'net zero' emissions to meet climate goals, and the International Energy Agency has unveiled a plan to get there.
For tree based removal of CO2 would demand between 0.4 and 1.2 billion hectares of land. That’s 25% to 80% of all the land currently under cultivation. How will that be achieved at the same time as feeding 8-10 billion people around the middle of the century or without destroying native vegetation and biodiversity?
If we add technological removal, it may be termed as investment with no return.
If we are purly dependent on plantation, growing billions of trees would consume vast amounts of water – in some places where people are already thirsty. Increasing forest cover in higher latitudes can have an overall warming effect because replacing grassland or fields with forests means the land surface becomes darker. This darker land absorbs more energy from the Sun and so temperatures rise. Focusing on developing vast plantations in poorer tropical nations comes with real risks of people being driven off their lands.
And it is often forgotten that trees and the land in general already soak up and store away vast amounts of carbon through what is called the natural terrestrial carbon sink. Interfering with it could both disrupt the sink and lead to double accounting.
Hi fellow students and scientists.
Im studying organic carbon levels and its origins in deep sediment cores from seagrass meadows sampled along the swedish Skagerrak coast. One core was successfully dated with C14, and the oldest section seems to be well within the Littorina sea period.
This site has apparently never been above sealevel, according to geodata since the last glacial ice cover. So I wonder, is it possible that the oldest part (thick, brown clay layer of organic and terrestrial carbon) is ackumulated humus transported by the glacial melting and subsequent runoff on the Swedish west coast?
I read in an article that during the Littorina sea period, there was indeed much runoff from land but nothing was mentioned about organic carbon - just inorganic.
My samples were treated with acid to remove inorganic remains. If there's anybody here with knowledge on postglacial sediments, Id love to hear what you think :)
The core profile can be summarized as follows:
1. Seagrass sediment section: Zostera marina.
~0-60 cm slice depth (decompressed).
Age 0-1700 BP.
Exclusively marine signal, from C/N ratio & isotopes.
2. Grey clay section: much rocks and shells.
~65-95 cm slice depth (decompressed).
Age 1700-3800 BP.
Both marine and terrestrial signals, C/N ratio & isotopes.
3. Brown clay section: small amount of rocks.
~105-130 cm slice depth (decompressed).
Age 3800 - 8092 BP.
Exclusively terrestrial signals, C/N ratio & isotopes.
Thank you in advance!
I need to build a model with meteorological data and terrestrial maps and prefer the output to be in the form of maps. I studied ML but I want to design a unique method. Which references or models can help me?
Kindly, name some reliable/popular field survey technique employed for amphibians (frogs) & terrestrial skinks (scincidae) in tropical forests. Thanks a ton.
Anomalous phenotype; polydactyly, adactyly, hyperregeneration, trematodes & mutations are observe in amphibians. Similarly, beside the the aforementioned reasons what are other associated phenomenon responsible & may suspected to influence such developments in terrestrial skinks (Scincidae) as well. Please suggest, thanks a ton.
In some crude oils or source rocks reported in previous publications, it is sometimes mentioned that the organic matter exhibite an pararent contribution of bacterial reworking of terrestrial organic matterial. So, which biomarkers are typical compounds resulting from bacterial reworking of terrestrial organic material ? In addition, which parameters can qualitatively characterize the degree of bacterial reworking ?
I would gratefully appreciate tutorials on processing Terrestrial LiDAR Data. I use the CLOUD COMPARE software to process the data in FLS (FARO TLS) data format. Cloud compare supports importing fls data as point clouds. But I am struck up with wat next. Going through different video tutorials which mostly explains step by step procedures, it seems inconsistent on the sequence of steps to be followed especially using the data as intensity or scalar value etc....
To illustrate an example, in optical remote sensing, we get the data as DN values, then we convert it to radiance and finally to reflectance (though currently many products are directly provided as radiance and reflectance).
In a similar fashion, it would be good if some one can suggest how a point cloud can be ultimately converted to elevation (with respect to WGS 1984 - orthometric). we have also carried out DGPS survey to generate tie points so as to generate orthometric height.
After downloading the data (JPL/CSR/GFZ) from ftp://podaac-ftp.jpl.nasa.gov/allData/tellus/L3/land_mass/RL05/netcdf/ to calculate TWS (Terrestrial Water storage) do we need to do any additional post-processing without multiplying with the scaling factor? Especially before using the TWS to calculate groundwater level or drought severity index"?
Hi everybody! Does anyone may suggest me some useful references (papers, books) for the interpretation of the signals emitted from the organic matter preserved in the sediments? Can be great to find a sort of table reporting the different kinds of organic matter (e.g., algal, terrestrial) and their response under specific emission filters.
Thanks in advance,
Generally forest ecosystems are often developed on poorly fertile soils where the plant available pools of nutrient cations are frequently very low, but the content of available potassium for a natural terrestrial forest stand shows a very high value of 671.89 kg/ha using the standard method for the soil chemical analysis, is it natural for the soils of a terrestrial forest patch?
Colonization of Mars and the terrestrial ocean-bottom probably runs parallel. There is a new space competition in human astronautic goals, and there is no competition to build settlements on the bottom of the sea.
For my final year thesis I require data on the average body mass of terrestrial predators and their prey. I have come across many papers which have used such data sets however, the data is not provided or I cant access it.
Thank you in advance for any help.
Storage components such as soil moisture, snowpack, groundwater, and surface water are poorly known at the sub-watershed scale due to a lack of well-distributed and continuous in situ networks. To ‘predict’ Spatio-temporal change in terrestrial water storages which hydro- and land surface models are more accurate and feasible at a local scale?
I want to measure the metabolic rate and water loss in amphibians, usually frogs and salamanders, that have different life histories. And, I want to build a chamber that I can use for aquatic and terrestrial species or life stages. I want them to work for both because the idea is to take measurements in the field and the system itself is already large.
I am starting to work with physiology, so any advice for the chamber or how to measure metabolic rate is welcome. Thanks!
I would like to promote a discuss if the recent global climate changes can influences microsporogenesis, microgamatogenesis, megasporogenesis and megagametogenesis. I was wondering, based on the million years of terrestrial plant existence, if the plants can adapt the sporogenesis and gametogenesis for the possible changes in climate. Also, what is you thought about the possible plasticity in crop plants?
The goal: i want to register crop point clouds and spectral information in a plot of the field.
The data detail:
1.The crop point clouds will be obtained by terrestrial Lidar (or UAV with rgb using SFM method) in a plot which is of high quality, you can see the accurate 3D structure of the crop.
2. The spectral information of crop will be obtained by UAV with Multispectral camera.
This is a field experiment, and i am a rookie in this field, I hope you can give me some suggestions, if it is some literature, it would be better.
Thank you !
Does anyone here know where to obtain estimates of paleo land areas for continents? I need data for the Cretaceous-Paleogene boundary and/or early Paleocene for each continent individually. While paleomaps are relatively easy to come by I haven't been able to find estimates for land areas although I assume such estimates exist.
I have designed an antenna to operate at 14.25 GHz( 14 to 14.5 GHz)uplink frequency of Ku band with linear polarization. what kind of application is suited for my designed antenna? and reference paper pls suggest me.
I learned from the literature that Sargassum sp. can directly secrete DOC in shallow seas, so I want to know whether large submerged plants in the lower terrestrial waters can directly release DOC, and it releases DOC what is the physiologically reason?
Global warming affects many processes in biological ecosystems. Different species of flora and fauna change their habitats and geographical areas according to climate change and specific geographical environments. Areas of occurrence of specific species, for example insects in terrestrial areas and fish and arthropods in the seas and oceans, change. Bird habitats change, so migrations of some bird species may also be subject to modification. In the situation when forest areas dry out and turn into steppes and deserts, changes in natural habitats and areas of occurrence of species change and concern simultaneously many species of flora and fauna.
Do you agree with me on the above matter?
In the context of the above issues, I am asking you the following question:
What changes in natural ecosystems are caused by the ongoing global warming process?
I invite you to the discussion
Thank you very much
I am currently conducting research on ecological aspects of juvenile crabs of the species Cardisoma crassum. I need information on related species.
Dear RG members,
I want to get information about the foods consumed by a few terrestrial insects; So I need to extract the contents of their stomachs. What is your propositional method that is applicable to extract these contents?
For a client I need to investigate the several remote sensing options to count individual rubber trees for a plantation in west Africa.
The total area to be surveyed is 20 000 hectares. Rubber tree canopies are difficult to delineate due to their complex canopies, unlike oil palm trees. The client has tried surveying using drone images before but without success.
The options I came up with so far:
High resolution satellite imagery
- 0.3m worldview 3 images.
Satellite imagery would be the most cost effective but considering the complex canopy structure (see attached image) I don't see this as a viable option.
- terrestrial lidar scanning:
Pros: High density pointclouds of individual trees.
Cons: Very time consuming, need several lidar instruments, need more manpower, .
- airborne lidar scanning (helicopter or plane ?)
Pros: fast, reliable, large area cover
- ATV lidar scanning?
LiDAR mounted on drones.
Cost effective, but can be unstable in windy conditions, limited flying range, and battery duration.
Anyone has any experience with such acquisitions and any idea of the costs and hours such acquisition takes?
happy to hear your thoughts.
Iodine is essential for human health, it is
essential element in the human diet and a deficiency can lead to a number of health outcomes collectively termed iodine deficiency disorders (IDD). The geochemistry of iodine is dominated by its volatility with volatilisation of organo-iodine compounds and elemental iodine from biological and non-biological sources in the oceans being a major component of its global cycle. As a result of the dominant oceanic source, iodine is strongly enriched in near-coastal soils, however, the major zone of marine influence generally stretches to only 50–80 km inland and terrestrial sources of volatilised iodine, from wetlands, soils and plants are also an important aspect of its global geochemical cycle. Iodine in soils is strongly bound with transfer factors from soil to plants being generally small and as a consequence there is only limited uptake of iodine through the plant root system. It is likely that uptake of atmospheric iodine by the aerial parts of plants is an essential process and, along with iodine deposited on plant surfaces, is a major source for grazing animals. Human intake of iodine is mainly from food with some populations also obtaining appreciable quantities of iodine from drinking water. Plant-derived dietary iodine is generally insufficient as evidenced from the low dietary iodine of strict vegan diets. Seafood provides major iodine-rich dietary items but other inputs are mainly from adventitious sources, such as the use of iodised salt and from dairy produce, which is a rich source mainly due to cattle-feed being fortified with iodine, and to the use of iodine-containing sterilants in the dairy industry. While the distribution and geochemistry of iodine are reflected in the global distribution of IDD, the recent upsurge of IDD in developed countries would seem to reflect changes in diet.so why iodine is essential?
Looking to connect with any research, papers or groups using remotely triggered stereo cameras to create 3 dimensional pictures of wildlife and gather data on cryptic species. Wanting to set up a system similar to the BRUV (baited remote underwater video) but for terrestrial systems, possible using a downward facing camera?
I'm thinking someone out there is probably already doing this?
Please see question above. Thanks for your response.
By this I mean that vision and compute technology appears to drive current and near-term environmental awareness and subsequent knowledge. So for example, whether an image is derived from a geo-satellite or field microscope, and to include all other considerations; is not a single picture grid theoretically standardized regarding its capture, so that a uniform data interpretation across the material panoply is possible?
I am focused on proximal terrestrial agricultural sensing, but I don’t see a limitation theoretically in conceptualizing a system of standard projected optical understanding which extends across the anthropogenic artifact and controlled conditions.
I have TLS (terrestrial) and ULS (UAV based) point cloud which I want to calculate Vertical Complexity Indices using forestR R package. But according to manual, input data must have XYZ coordinates and Vegetation Area Index (VAI) in order to run this package. Can anyone please let me know if there is any relatively simpler way to calculate VAI?
We know that some terrestrial vertebrates has exposed teeth,some of them are for sexual displaying,some are for a weapon or a tool,but most terrestrial vertebrates' teeth are cover by lips,the surrounding in the mouth and ouside is different.so is there any special mechanism for maintaing the exposed teeth of those animals?
I am currently working on a particular deepwater sedimentary system, which probably records processes and deposition within a forearc setting. The effects and deposits from a nearby volcanic terrane (both terrestrial and sub-aqueous eruptions) are clear throughout the succession. I have found a number of comparable systems in the literature, but there seems to be a general lack of information concerning this type of setting . If anyone has any good examples of a such a system, which I have not already found, it would be greatly appreciated.
The terrestrial organic matter injected into the sea through estuaries may be the important hydrocarbon generating parent material of natural gas in sea areas.
My point is that the lost sink is so great that the amount of measured or estimated emissions after impoundment doesn't really matter because either way the net loss is going to be high. If possible kindly suggest me something, because it means that the condition of the flooded land is the most critical factor in net emissions after impoundment. Is that correct?
Often Oil spills on the terrestrial landscape including the wetlands. This could be either operational or as a result of sabotage. I will like to know if there is a technology that can be used to detect in near real time and monitor such (potential) spills. This takes into consideration the fact that such spills could occur in a thick bush or vegetated areas. Any thoughts here would be appreciated.
I've encountered an Ostracod species within Beech leaf litter from Aberdeenshire, Scotland and would like to know if:
- other researchers have encountered leaf litter Ostracods in the UK/Ireland/ Europe.
- there is a key to terrestrial species.
- anyone would be willing for me to forward to them a number of specimens for possible identification?
I am looking for water quality effects on the toxicity to plants when diuron is used as an algaecide in water. I have seen documentation about use as a herbicide in terrestrial environments but can't find anything about aquatic ecosystems.
Low pH and high temperatures appear to be a factor but I haven't found any studies that look at these (or any other) factors - only dosage tolerance with little reference to conditions.
I have been comparing the community structure of aquatic plants and terrestrial herbs since they are both herbs but growing in so different habitats.
I want to see what is the key point to rule their community structure. As is well known, the precipitation is important for terrestrial herbs. Light and nutrient are also important for species composition in the terrestrial plant community. While for aquatic plants, water availability is no more limiting but water depth comes in as an new factor. Light and nutrient become more important.Therefore, it is something that can be testified in controlled systems.
What do you think which one can be the key point for plant community?
According to Noam Chomsky, "the Martian language might not be so different from human language after all.” And, "if a Martian visited Earth, it would think we all speak dialects of the same language, because all terrestrial languages share a common underlying structure” — he must mean "universal grammar." Others also believe that since the laws of the universe are supposedly the same everywhere, the language alien civilizations use might be fundamentally similar. Stephen Krashen, on the other hand, wrote "It is possible that alien language will be completely different from human languages." Do you think alien language would be similar to or different from human language?
I am working on terrestrial LiDAR modelling and simulation, and I was wondering how to prepare the correct model of LiDAR rotation. I don't understand how laser scanning pattern looks like. I know that most of the 3D sensor has 360 degree horizontal FOV and about 27 degree vertical FOV but I don't know how to connect these two things. Based on pulse rate and rotation rate I calculated degree between pulses but only in XY plane (horizontal scanning). How to add also vertical scanning? Could you give me some examples of scanning pattern and how to simulate LiDAR scanning based on LiDAR's parameters?
Could you use additional ideas on your microplastic research?
I'm happy to share a draft of a project on impacts of microplastic on terrestrial biodiversity & function. It received positive feedback, but we can't execute it due to changes in my career perspectives. Please feel free to copy or chery pick whatever suits best your interest. The important is that research goes on. ;)
Terrestrial water storage (TWS) changes are calculated using GRACE data given as TWS = Surface water + Soil water + Snow.
How to calculate TWS from CMIP data ? what parameters can i use from GCMs?
Is there any possibility to calculate TWS from water balance equation?
