Snow depth and SWE

Using repeat, high-resolution DEMs to capture the spatiotemporal evolution of snow depth and snow water equivalent (SWE) on a regional scale.

Motivating questions:

  • How much snow falls in the Western U.S. each winter?
  • Are downscaled reanalysis products capturing true spatiotemporal evolution of snow?
