This resource includes the 25-year return level extreme maps of 4-km gridded snow water equivalent (SWE) and 7-day snowmelt and runoff potential (RP) and over North America. The maps are developed by using 25-km gridded historical and future simulation data sets from the North American Coordinated Regional Climate Downscaling Experiment (NA-CORDEX) under the Representative Concentration Pathway [RCP] 8.5. For full details, please see Cho et al. (2021) in Geophysical Research Letters.
