The Airborne Snow Observatory (ASO) is an airborne suite of remote sensing instruments used for measuring snow properties such as snow albedo, snow depth, and snow water equivalent. ASO consists of a CASI 1500 imaging spectrometer and a Riegl Q1560 scanning lidar. The CASI spectrometer operates across the 380-1050 nm and is used to retrieve spectral albedo. The Riegl Q1560 lidar operates at the 1064 nm wavelength and is used to measure surface elevation to determine snow depths. Snow depth measurements are provided at a spatial resolution of 3m and 50m, while snow water equivalent measurements are only provided at a resolution of 50m.

RAMS consists of two radiometers: the Total Solar Broadband Radiometer (TSBR) and the Fractional Solar Broadband Radiometer (FSBR). The TSBR operates in the 0.224 to 3.91 μm range while the FSBR operates between 0.68 to 3.3 μm. It has a response time of about 60 msec and can provide measurements about every 5 m for aircraft speeds around 75 m/s. RAMS is typically used for airborne operations, but it can be used to collect ground-based measurements as well.
