Description:

Understanding the distribution of snow-water equivalent (SWE) is crucial for the prediction of water resources in the western United States. Backward running SWE reconstructions use satellite- observed, binary snow presence imagery to reconstruct SWE mass estimates. This approach relies on the connection between snow timing and peak SWE, yet few studies have directly examined this relationship. Here, we investigate the strength and spatiotemporal variation in this relationship across the western United States and Alaska. Within the SNOTEL network (n = 611 sites), we find that most variance in peak SWE is explained (median R2 = 0.64, σ = 0.18) by, in order of explanatory skill, the timing of snow
