The Airborne Snow Observatory (ASO) is an airborne remote sensing system that measures snow properties, including snow albedo, snow depth, and snow water equivalent. ASO includes a CASI 1500 imaging spectrometer and a Riegl Q1560 scanning lidar. The CASI spectrometer operates across 380-1050 nm and is used to retrieve spectral albedo. The Riegl Q1560 lidar operates at 1064 nm and measures surface elevation to determine snow depth. Snow depth measurements are provided at spatial resolutions of 3m and 50m, while snow water equivalent measurements are available only at 50m.
