The cryosphere is the frozen water part of our planet. The cryosphere components of snow and glacier are more general over the Indian Himalayan region which are important sources of north Indian rivers. The group primarily focusses on Glaciology and snowpack characterization over the Indian Himalayan region for last two decades. Monostatic and Bistatic Polarimetric Synthetic Aperture Radar (SAR) data are used for the cryosphere applications. PolSAR, InSAR, PolInSAR techniques are mostly used. Field Expeditions to the Himalayan region synchronized with the satellite passes are also a part of the activities of our research group.

Research Areas

  • Algorithms for snow pack parameters like snow wetness, density and grain size using fully polarimetric Synthetic Aperture Radar (SAR) data.
  • Studying the Himalayan glaciers movement using interferometry and offset tracking methods.
  • Algorithms for snow depth measurements by combining active and passive microwave remote sensing data.
  • Methodology for snow and glacier melt run-off estimation.
  • Algorithms for snow cover mapping using remote sensing techniques.
  • Temporal remote sensing data analysis for glacier mapping and glacier retreat/surge.
