Researchers use Lasers to Measure Snowpack

Researches are using lasers to determine snowpack. These images show measurements of snow water equivalent (top) and snow albedo, or reflectivity (image) for the Tuolumne River Basin in California's Sierra Nevada in April, 2013. Albedo shows the percentage of sunlight reflected back; the lower the albedo, the faster the snowmelt rate and runoff.

Scientists in Colorado are working to improve runoff forecasting in the West so water managers can meet growing needs in the future. A growing population coupled with climate change means every drop will count. Scientists are mapping terrain and snow with lasers to provide a more accurate picture of the snowpack. It's called the NASA JPL Airborne Snow Observatory. Aspen Public Radio’s Marci Krivonen spoke with Jeff Deems, a research scientist with the University of Colorado, Boulder. He’s involved with the project.
