Description

This data set contains spatially and temporally complete (STC) raster images of snow cover and snow surface properties from 1 October 2000 through 30 June 2022 for the High Mountain Asia region. The data are derived from the MODIS Snow Covered Area and Grain-size (MODSCAG) and MODIS Dust Radiative Forcing in Snow (MODDRFS) data sets using historical surface reflectances from MODIS/Terra as input.

Variables include snow fraction (viewable and canopy-corrected); optical grain size; snow albedo (with and without light-absorbing particles); and energy flux to the snowpack from light-absorbing particles.
