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.
Volunteer Scientists Validate Rain and Snow Estimates
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.
Chasing Snow – Stories of Wonder, Tradition, and the Science of Winter
Join us for an evening of captivating stories that explore our connection to winter. From the wonder of snowfall to the traditions it inspires, and the science that unravels its mysteries, 'Chasing Snow' celebrates the many ways winter shapes our lives. Through...
A New Tool Can Help Protect California and Nevada Communities from Floods While Preserving Their Water Supply
DRI’s Anne Heggli is partnering with the National Weather Service to understand flood risk from rain-on-snow storms in real-time, protecting communities and enabling water conservation throughout Nevada and California.
Community Scientists Needed: Help Improve Winter Weather Predictions
Community members across Utah, the Great Basin, and around Lake Erie and Lake Ontario are invited to join people across the country in contributing winter weather observations. The data is collected by scientists for a NASA-funded project that seeks to improve the accuracy of winter weather predictions.
Wildfires Are Increasingly Burning California’s Snowy Landscapes and Colliding with Winter Droughts to Shrink California’s Snowpack
A DRI-led team examined what happens to mountain snowpacks when sunny, midwinter dry spells occur in forests impacted by severe wildfire.
Study Develops Framework for Forecasting Contribution of Snowpack to Flood Risk During Winter Storms
A new study provides the first framework for a snowpack decision support tool that could help water managers prepare for potential flooding during rain-on-snow events, using hourly data from existing snow monitoring stations.
DRI welcomes new graduate students to Reno and Las Vegas campuses
Each year, the Desert Research Institute (DRI) welcomes new graduate students from the University of Nevada, Reno (UNR) and University of Nevada, Las Vegas (UNLV), who work under the direction of DRI faculty on our northern and southern campuses to conduct...
