DRI scientists Guo Yu, Meghan Collins, Monica Arienzo, and Anne Heggli co-authored a new study that examines how Mountain Rain or Snow is helping improve weather forecasting models. The citizen science project collects observations of precipitation from community volunteers across the country to further scientific understanding of the environmental variables impacting where precipitation falls as either rain or snow. This information is critical for informing avalanche forecasting, road safety, and water resources management.
