Listed in NASA Data Portal
Notice: Due to funding limitations, this data set was recently changed to a “Basic” Level of Service.
Description
Learn more about what this means for users and how you can share your story here: Level of Service Update for Data Products . This data set contains snow pack properties, such as depth and snow water equivalent (SWE), from the NOAA National Weather Service's National Operational Hydrologic Remote Sensing Center (NOHRSC) SNOw Data Assimilation System (SNODAS).
SNODAS is a modeling and data assimilation system developed by NOHRSC to provide the best possible estimates of snow cover and associated parameters to support hydrologic modeling and analysis.
