Sar Based Three-Dimensional Surface Deformation Monitoring of High Mountain Glaciers

Monitoring of mountain glaciers using SAR interferometry is challenging, yet it is necessary to improve our understanding of glacier dynamics in a changing climate, by estimating their precise movements. Although there are significant difficulties of spatial and temporal decorrelation for observing mountain glaciers, multiple aperture interferometry (MAI) can be a promising solution compared to other existing methods. In this study, we will present temporal variations of Himalayan glaciers' behavior focusing on the velocity estimation and glacier outline mapping. These results will be provided for estimating the rate of glacier melt, and in turn play an important role in better understanding the hydrology and climate change in the Himalayan region.
