High-resolution satellite remote sensing (SRS) is used to study large glaciers with necessary accuracy and detail. For effective studies of large glaciers, data obtained from Landsat satellites (resolution 15-30m) for the period up to 2015 and recent data from 2020 – of the SPOT satellite (resolution 1-1.5m) and several satellite data archives are used. Quantitative characteristics of large glacier retreats are determined to study the negative impact of climate change on glaciers in detail. Data quality control/quality assessment (QA/QC) is carried out to ensure reliable outputs, using ground based observations (GBO) data sets. Glacier retreat regression equations are utilised to determine the likely dates of large glaciers' full melting and the total melting of glacial basins under the worst scenario of current climate change.
