Snow Depth Duration
This application creates a table of duration of snow cover for a given day. The default example answers the question, "When there is snow on the ground for Christmas in Ames, how long does it stick around for?"
The dataset used for this application is based on NWS COOP observations, but also contains estimates when data is missing.
