This study investigates the different performances between Compact-Polarimetric (CP) and Full-Polarimetric (FP) SAR to retrieve multiple crop growth parameters including Vegetation Water Content (VWC), Leaf Area Index (LAI), height, and dry biomass. The objective is to study at which conditions the CP SAR can obtain comparable retrieval accuracy as...

Nowadays, a wide range of applications require near-real-time Surface Soil Moisture (SSM) data at high spatial resolution. However, operational passive microwave systems like SMOS and SMAP can only acquire such information at a relatively coarser resolution. Therefore, several downscaling algorithms have been developed to address this issue and pro...

Satellite SAR-based soil moisture retrieval during the crop growth cycle is a challenging task due to the complex interaction between the crop elements and radar signals. Such interactions make it difficult to reliably retrieve the top layer (0−5 cm) soil moisture prevailing during the crop growth cycle. We propose an approach to estimate soil mois...

On behalf of the European Commission, the European Environment Agency has commissioned the development and real-time production of the Copernicus High Resolution Snow & Ice products (HRSI), including a snow cover component to address these needs. In particular, this service provides a canopy-adjusted fractional snow cover (FSC) at 20 m resolution...

Forest cover is a crucial factor that influences the performance of optical satellite-based snow cover monitoring algorithms. However, evaluation of such algorithms in forested landscapes are rare due to lack of reliable in-situ data in such regions. In this investigation, we assessed the performance of the operational snow detection (SCA) and frac...

A deadly cascade A catastrophic landslide in Uttarakhand state in India on February 2021 damaged two hydropower plants, and more than 200 people were killed or are missing. Shugar et al. describe the cascade of events that led to this disaster. A massive rock and ice avalanche roared down a Himalayan valley, turning into a deadly debris flow upstre...

Remote sensing is an indispensable tool for Earth observation over large areal extent. Snow cover extent monitoring has been one such application where microwave sensors have been a popular choice due to their sensitivity toward the dielectric property. Snow is a dynamic matter since its dielectric state is dependent on climatic factors prevailing...

Recent studies have highlighted the depleting trend of snowfields and receding glaciers in parts of the Hindu-Kush Himalayan (HKH) region. It is believed that the onset of this recession commenced during the mid-19th century (Bolch et al., 2012). A number of glaciers situated outside the Karakoram region have demonstrated ablation patterns. Since t...

Quantifying seasonal variation of Touzi asummetry for monitoring snow cover over the Indian Himalayas
Article
Full-text available
Monitoring of snow cover over large areal extent requires the use of remotely sensed satellite data. Conventional snow cover mapping algorithms using SAR data have seldom utilized target scattering information for land cover characterization. In this paper, an approach is proposed for snow cover mapping that utilizes the Touzi eigenvalue-eigenvecto...

Polarimetric synthetic aperture radar is expected to distinguish wet snow from bare ground. However, since both of them show the surface scattering, that is sensitive to incidence angle, it often fails in the distinction in mountainous areas. In this paper, we propose an adaptive distinction method by using quaternion neural networks. In the ALOS-2...

In this paper, we have proposed a new decomposition technique for compact polarimetric (CP) synthetic aperture radar (SAR) data. In the proposed decomposition, the odd and the even bounce scattering powers and are, respectively, obtained by combining the powers received in the opposite-sense circular (OC) polarization and the same-sense circular (S...

Cryosphere plays a crucial role in regulating local and global climate. Glaciers form an important component of this frozen part of the Earth's system. They exist over a prolonged period and are largest reservoir of freshwater on Earth. The meltwater from the glaciers during warmer seasons contribute to the river systems in absence of other sources...

Model-based decompositions have gained considerable attention after the initial work of Freeman and Durden. This decomposition which assumes the target to be reflection symmetric was later relaxed in the Yamaguchi et al. decomposition with the addition of the helix parameter. Since then many decomposition have been proposed where either the scatter...

The angle of rotation (θ) of any object about the line of sight (LOS) is known as the polarization orientation angle (OA). The OA is found to be non-zero for undulating terrains and man-made targets oriented away from the radar LOS. This effect is more pronounced at lower frequencies (eg. L- and P-bands). The OA shift is not only induced by azimuth...

High Circular Polarization Ratio (CPR) was thought to be a robust diagnostic of water-ice on the lunar surface. Recent researches have reported such findings on walls, floors, and proximal ejecta of impact craters, as well as on sunlit zones. These signatures could not be explained with water-ice as the probable cause. In an attempt to explain such...

High values of Circular Polarization Ratio (CPR) tending to and rising beyond unity were thought to be robust diagnostics for water-ice. Such sightings were expected to correlate with regions of permanent shadow on the lunar surface. Recent researches have reported such findings on walls, floors, and proximal ejecta of impact craters, as well as on...
