Service Description: (1) Estimated snow water equivalent (SWE), in mm for historical and percent change for future and (2) snowpack precipitation fraction (sometimes called snowpack vulnerability), in percent. (1) is just snowday fraction (percent of precipitation that comes in as snow) multiplied by precipitation, so it is an upper estimate of SWE because it doesn't account for melt, ablation, or redistribution. (2) is the ratio of October to March SWE to October to March precipitation. This includes a historical map, and 2020s (2010-2039), 2050s (2040-2069) and 2080s (2070-2099) changes.
