Data for: Ascertaining glacier dynamics and geodetic mass changes in the Pangong Region of Trans-Himalayan Ladakh using remote sensing data
Description
The data attached with this article is related to the glacier recession, frontal retreat, physiographic characterization of glaciers, glacier-wise geodetic mass changes, potential glacier bed overdeepening vis-à-vis proglacial lake evolution, and comparison of existing glacier inventories in the Pangong Region of Trans-Himalayan Ladakh, India. A paper pertaining to this analysis already stands published in Frontiers in Earth Science [https://doi.org/10.3389/feart.2021.748107]. The ZIP file contains data pertaining to the following aspects of glacier recession in the Pangong Region: 1. Glacier-wise characteristics 2. Glacier outlines of 1990 and 2019 3. Glacier outlines of existing glacier inventories and this study 4. Glacier-wise geodetic mass changes 5. GlabTop model input and output

Steps to reproduce
The knowledge pertaining to glacier changes in the Pangong Region was generated by analyzing the remote sensing data (satellite images and digital elevation models) in a GIS environment. Analysis was done in QGIS 2.10.1 and ESRI Arc Map 10.1 Manual delineation of satellite data from USGS and Planet Labs helped to generate glacier outlines of 1990 and 2019. TanDEM-X DEM was used for topographic characterization. Multi-date DEMs (SRTM of 2000 and TanDEM-X of 2019) were used to quantify geodetic mass changes in the Pangong Region. GlabTop model was used to simulate glacier bed overdeepenings and ice thickness. Since this research is typically a remote sensing-based work, it could be replicated for the other inaccessible glaciated mountain landscapes.
