AB: Researchers at the Desert Research Institute and the NASA are conducting research aimed at improving water supply forecasts in the Truckee River Basin using NASA Earth Science Data Products. The primary goals of this project are: 1) to demonstrate the use of fractional snow covered area (SCA) observations derived from NASA's Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS) for analyzing the temporal and spatial distribution of error associated with modeled SCA; and 2) demonstrate how fractional SCA observations can be used to improve operational streamflow forecasts derived from PRMS (Precipitation Runoff Modeling System), a USGS precipitation-runoff model. Initial results indicate that there are substantial differences between spatial and temporal distributions of PRMS simulated SCA and MODIS derived fractional SCA. When MODIS fractional SCA information is used to adjust model parameters, streamflow simulations are improved.
