    • ABoVE: Passive Microwave-derived Annual Snowoff Date Maps, 1988-2016

    Metadata Updated: June 4, 2024

    This dataset provides annual maps of the snowoff (SO) date from 1988-2016 across Alaska and parts of Far East Russia and northwest Canada at a resolution of 6.25 km. SO date is defined as the last day of persistent snow and was derived from the MEaSUREs Calibrated Enhanced-Resolution Passive Microwave (PMW) EASE-Grid Brightness Temperature (Tb) Earth System Data Record (ESDR) product. The spatial domain was intended to match MODIS Alaska Snow Metrics and extend its temporal fidelity beyond the MODIS era. SO date estimates were compared to snow depth measurements collected at SNOTEL stations across Alaska and to three SO datasets derived from MODIS, Landsat, and the Interactive Multisensor Snow and Ice Mapping System (IMS).

    There are 30 total files in GeoTIFF (.tif) format, one file for every year from 1988-2016 and a fractional water mask file.
