SRTM GL1 v3 (30 m)#

The Shuttle Radar Topography Mission 1 arc-second global DEM, version 3 (void-filled): the February 2000 C-band radar surface, 60°N to 56°S, EGM96 geoid. Kept under its own name because so much of the snow literature is built on it; NASADEM is the same mission reprocessed. OpenTopography serves it without an account, and also as a WGS84-ellipsoid copy (ellipsoidal=True) converted with the EGM96 geoid, for differencing against ICESat-2, GNSS or lidar heights.

import easysnowdata as esd

aoi = (-121.94, 46.72, -121.54, 46.99)   # Mount Rainier
dem_da = esd.terrain.dem.load(aoi)
