The NC CASC Climate Science Support Platform has developed a new R-Shiny app to quantify daily snowfall and rainfall quantities from total daily precipitation data in both observations (gridMET) and future projections (MACAv2-METDATA). Often the observed and projected precipitation data do not distinguish between snowfall and rainfall. Based on our best current understanding, this new application uses relationship between the phase of precipitation and the temperature and relative humidity metrics to quantify proportion of daily precipitation falling as rainfall or snowfall. More information on the app can be found at https://nccasc.shinyapps.io/Rainfall_Snowfall/.
