20 km annual wet day totals for Alaska, 1980-2100

This dataset consists of single band GeoTIFFs containing total annual counts of wet days for each year from 1980-2100 for one downscaled reanalysis (ERA-Interim, 1980-2015) and two downscaled CMIP5 global climate models driven under the RCP 8.5 baseline emissions scenario (NCAR-CCSM4 and GFDL-CM3, 2006-2100), all derived from the same dynamical downscaling effort using the Weather Research and Forecasting (WRF) model (Version 3.5). A day is counted as a "wet day" if the total precipitation for that day is 1 mm or greater.

Purpose: This dataset was created to support the Arctic EDS, an online web tool resource created to serve engineering-oriented climate projections, inspired by the historical publication titled, "Environmental atlas of Alaska."
