Snow-water equivalent data were derived from the California Department of Water Resources snow survey (https://cdec.water.ca.gov/) and the Natural Resources Conservation Service's SNOTEL sites in WA, OR, CA and ID (https://www.wcc.nrcs.usda.gov/snow/). Anomalies of April 1 snow-water equivalents (SWE) for the CCE, calculated as an area-weighted average of data from 5 ecoregions. SWE is a measure of the total water available in snowpack. Measurements on April 1st are considered the best indicator of maximum extent of snowpack.
