Questions related to Space Weather
I want to study some events encountered by the Parker Solar Probe (PSP) satellite using different statistical tools. I have downloaded data from the websites recommended by different researchers, however I am facing a problem reading the .cdf file format of the data. If you provide all available data (in minutes resolution) of some specific event days, it would be a great help for me.
We performed a correlation analysis of solar wind speed (Vsw) with z-component of interplanetary magnetic field (Bz) during geomagnetic storm events with different strengths. We found varying results: a bit larger correlation coefficient for some events, but also a moderate association during some events. What sort of results can we expect?
Hi, I use two models to calculate the atmosphere density during a satellite orbit propagation. The two models are NRLMSISE-00 and DTM-2000. To feed the models I'm using Space Weather Data provided by Celestrak (https://celestrak.com/SpaceData/SW-Last5Years.txt). I was surprised the see that both adjusted and observed data are provided in this file. I found that observed data must be used for NRLMSISE-00 model. However, I didn't see any information about which type of data to use (i.e., adjusted or observed) for DTM-2000. Does anyone have the answer or a reference?
Parker Solar Probe, NASA's mission for a better understanding of the Sun's environment, is continuously providing data from different encounters. Past encounters were especially during the solar minimum period. I am really curious to know in detail why the study of fluctuation on the magnetic field and other solar wind parameters data during solar minimum period? What are the major advantages of its study? I am looking for descriptive answers. Please help. Thank you.
My main goal is to use Neural Networks to forecast Sunspot Numbers. Requesting the option of ANN or RNN seems simple enough. However, which is best to learn and utilize for a complete beginner? If there is a GitHub repository for similar Space Science topics based on Neural Networks, please link me to it. I'd be extremely appreciative.
Parker solar probe is providing data from different encounters. If we plot data over a distance (for eg: from 0.5 au to 0.17 au), it shows, towards the sun, interplanetary magnetic field increases. It has also positive correlation with solar wind density and temperature, however, slightly weak correlation was obtained for solar wind speed. I want to learn how solar wind parameters vary over a distance, and a physics associated with it. Need your suggestion (please suggest me some good articles, if available). Thank you.
I heard that some storm events can occur without any change in the Dst index. Significant change in solar wind parameters that are triggered by storms events, but, without any change in Dst? Is it true? If yes, can you please suggest some events (or articles) for example? I am really excited to plot them. Moreover, what are the possible reasons behind those effects?
Sunrises that occur usually every 11 years cause specific climate changes and weather anomalies on Earth. The effect of these solar suns is also the emerging effect of El Ninio in the oceans, changes and increasing the activity of water currents in the oceans.
Some research subjects of this issue relate the solstice of solar activity with human activity suggesting that in these years more dramatic political, economic and other events occurred.
On the other hand, paradoxically, in the last dozen or so years, the activity of Sun decreased. Despite the declining solar activity, the greenhouse effect on Earth is accelerating, and the ozone hole is expanding what can adversely affect human health and change natural ecosystems.
Do you know publications that describe this type of correlation? If so, please link to these publications.
In the light of the above, encouraging discussion, I turn to you with the following question: Does anyone of you investigate the question of the relationship of solar solstices to the events of the development of human civilization on Earth?
Please, answer, comments. I invite you to the discussion.
I wish you the best in New Year 2019. Best wishes
I've known that one of the unresolved problems is the Coronal heating problem and there are already many theories to explain the illogical temperature at the Corona. I need to know what are the other problems in the field of Solar Physics and what are the challenges to explain these problems?
Highlights on Space Weather, Space Climate, Terrestrial Weather, and Earth Climate.
I am asking this question in the context of evaluating solar beam irradiation on buildings at city scale.
I am wondering if those variations impact the amount of energy perceived by building, and therefor should be taken into account while evaluating how buildings are warmed up by the sun.
I need to generate seasonal snow cover area for the past 50 years based on available Snow cover products i.e) Modis, AVHRR, AWIFS data comparing with precipitation and temperature.
Space weather refers to geomagnetic storms, coronal mass ejections and other atmospheric disturbances--whether by random natural sunbursts or via man-engineered causes--which will nullify and destroy cyber and electric grid systems for upwards of 6 months.
Literature uses 1112 ESH for a year on GSO with north-south faced satellite. This can be found on:
"Degradation of thermal control materials under a simulated radiative space environment" by A.K. Sharma and N. Sridhara
"Evaluation of Thermal Control Coatings Degradation in Simulated Geo-Space Environment" by J. Marco and S. Remaury
and other publications. How does this value derives in detail? My approximations show results around 886 ESH.
I want a simulator to calculate the delay, energy efficiency etc for wireless sensor Networks (WSN) in space environment (space based missions).
And another thing is that, can we simulate effect of space weather on nodes if we send them in space?
I need to know the time-varying location, in terms of selenographic latitude and longitude, of the point where the line connecting the centers of the Sun and Moon intersects with the lunar surface, to the accuracy of second and kilometer, from 2000 to 2020. Thanks!
With signals in the UHF and VHF, the ionosphere is like a transparent medium (that is, it is like a vacuum). Is it safe to assume that ionospheric and space-weather effects do not interfere with these signals? If there is/could be a relationship between them, kindly discuss them and please support your argument with relevant literature if available? Thank you.
Because during these periods there is a significant fluctuations observed in solar wind plasma as well as space weather parameters.
In recent years I have observed increasing numbers of research students trained primarily to use sophisticated toolkits, such as large observational and experimental facilities, and/or large computer programs.
A disturbing number struggle to articulate the basic question addressed by their research, or why one should care about the outcome. Young scientists need to be trained to spend time formulating questions whose answers will guarantee advancement in our understanding.
Should we be driven mostly by tools at hand and by societal needs? Do curiosity and the strictures of The Scientific Method have a role to play? Or is scientific work now driven by those outside of science?
Having in mind that the f2-layer peak height in some instances during quiet and low solar activity conditions can be less than 300 km.
