Long Science in the Nevada Bristlecone Preserve

Ancient bristlecone pines have been collecting data for us for millennia. Anne Heggli’s research aims to provide a nearly microscopic look at how the climate in the Great Basin is changing, from hour to hour and season to season. With scientific monitoring equipment positioned from the floor of the Great Basin’s Spring Valley up to the peak of Mount Washington, her project examines temperature fluctuations, atmospheric information, and snowpack insights across the region’s ecosystems.

Blurring the Line Between Rain and Snow: The Limits of Meteorological Classification

A new study published in Nature Communications utilizes insights gleaned from DRI’s Mountain Rain or Snow project to evaluate why traditional weather forecasting struggles to identify the rain/snow transition line. The research was possible because thousands of community members across the U.S. contributed more than 40 thousand observations of the type of precipitation falling at their location.

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.
