Projected Decadal Averages of Monthly Snowfall Equivalent 771m CMIP5/AR5

These files include downscaled projections of decadal average monthly snowfall (water) equivalent (SWE) in millimeters for each month of the decades from 2010-2019 to 2090-2099 at 771 x 771 m spatial resolution. Each file represents a decadal average monthly mean. Output is available for the NCAR-CCSM4, GFDL-CM3, GISS-E2-R, IPSL-CM5A-LR, and MRI-CGCM3 models and three emissions scenarios (RCP 4.5, RCP 6.0 and RCP 8.5).

SWE estimates were produced by multiplying snow-day fraction ("fs") by decadal average monthly precipitation ("Pr") such that

SWE = (fs * Pr) / 100

Snow-day fraction data used can be found here: http://ckan.snap.uaf.edu/dataset/projected-decadal-averages-of-monthly-snow-day-fraction-771m-cmip5-ar5

Precipitation data used can be found here: http://ckan.snap.uaf.edu/dataset/projected-monthly-and-derived-precipitation-products-771m-cmip5-ar5

* Note: In Littell et al. 2018: "SWE" is referred to as "SFE" and "fs" is referred to as "PSF"
