-C-band RISAT-1 imagery for geospatial mapping of cryospheric surface features in the Antarctic environment
-HV was introduced to make use of the original two polarizations. In addition to the data calibration, transformed divergence (TD) procedure was performed for class separability analysis to evaluate the quality of the statistics before image classification. For most of the class pairs the TD values were comparable, which indicated that the classes have good separability. Fuzzy and Artificial Neural Network classifiers were implemented and accuracy was checked. Nonparametric classifier Support Vector Machine (SVM) was also used to classify RISAT-1 data with an optimized polarization combination into three land-cover classes consisting of sea ice/snow/ice, rocks/landmass, and lakes/waterbodies. This study demonstrates that C-band FRS1 image mode data from the RISAT-1 mission can be exploited to identify, map and monitor land cover features in the polar regions, even during dark winter period. For better landcover classification and analysis, hybrid polarimetric data (cFRS-1 mode) from RISAT-1, which incorporates phase information, unlike the dual-pol linear (HH, HV) can be used for obtaining better polarization signatures.

-Optical remote sensing of atmospheric total ozone with radiometers
Nov- 18520 percent on the most stable days. These differences can be attributed to a combination of large aerosol optical depths, diurnal variation of aerosol optical depth, the deviation from the assumed power law relationship coefficients. The ozone optical depths inferred experimentally from the Chappuis-band method have been used to determine more accurate aerosol optical depths as compared to those routinely to those routinely obtained by using model ozone vertical profiles.
