Abstract

In the paper, we discuss application of remote sensing methods to study Himalayan cryosphere in India. Satellite data in combination with field is used to develop models, which can estimate numerous glacier parameters as area, velocity, depth, mass balance, debris cover, glacier lakes and risk assessment of Glacier Lake Outburst Flood. Digital Elevation models are extensively used to estimate glacier mass balance at regional scale and have improved our understanding of spatial heterogeneity in mass loss. Surface velocity and slope are combined with laminar flow to estimate spatial distribution of glacier depth. This has significantly improved estimate of glacier stored water and glacier lakes. Applications of remote sensing data in mass balance and runoff models help in assessing the impact of climate change on water availability. These investigations suggest indispensable role of remote sensing techniques to understand Himalayan cryosphere. © 2020 Geological Survey of India. All right reserved.
