For creation of the PASR product, snow depth observations were used with the NSIPP model to reconstruct how much snow must have fallen to create the observed snow depth. In a similar manner, snow water equivalent available for spring runoff can be predicted by assimilating measurements of snow cover and other remote sensing observations into the NSIPP catchment-based land surface model. This project is in the development phase where various data assimilation methods are being tested against ground-based measurements in Alaska.
