This map shows daily snowpack estimates for the contiguous United States since October 2003. Using the dropdown menu above the chart – or clicking a state on the map – redraws the chart to show the snowpack estimate by day for the selected state.
This data set contains output from the 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.
