Overview

NSIDC DAAC will archive and distribute data products from the NASA Airborne Snow Observatory (ASO), a coupled imaging spectrometer and lidar system. Primary products are snow albedo, snow depth, and snow water equivalent (SWE) collected during airborne campaigns in the western United States and beyond. The imaging spectrometer quantifies snow albedo. The lidar is used to determine snow depth (relative to snow-free data sets) and quantifies SWE when snow depth is combined with observed and modeled snow density.

About the Project

NASA/JPL, with support from the NASA Terrestrial Hydrology and Applied Sciences programs, and in partnership with the California Department of Water Resources and other state and local entities, has developed the Airborne Snow Observatory (ASO), an imaging spectrometer and lidar system. The primary science objectives of the ASO are to:

  • quantify SWE and snow albedo for entire mountain watersheds
  • generate knowledge of snow properties and their spatial and temporal variability
  • provide inputs to water management models and systems of the future
