NOAA@NSIDC is pleased to announce the release of the Contribution to High Asia Runoff from Ice and Snow (CHARIS) Melt Model Output, 2001 – 2014 data set. The CHARIS project aimed to distinguish the specific contribution of seasonal snow and glacier ice melt in five major river basins of High Mountain Asia: Ganges, Brahmaputra, Indus, Amu Darya, and Syr Darya. CHARIS investigators developed a systematic way of using remote sensing, reanalysis, and in situ data to calibrate and run temperature index melt models.
