Historical and Projected Dynamically Downscaled Climate Data for the State of Alaska and surrounding regions at 20km spatial resolution and hourly temporal resolution (v1.1, August 2023)

This dataset contains historical and projected dynamically downscaled climate data for the State of Alaska and surrounding regions at 20km spatial resolution and hourly temporal resolution. Select variables are also summarized into daily resolutions. This data was produced using the Weather Research and Forecasting (WRF) model (Version 3.5). We downscaled both ERA-Interim historical reanalysis data (1979 - Oct 2015) and both historical and projected runs from 2 GCM’s from the Coupled Model Inter-comparison Project 5 (CMIP5): GFDL-CM3 and NCAR-CCSM4 (historical run: 1970-2005 and RCP 8.5: 2006-2100).

This dataset was updated to a version 1.1 in August, 2023 to retain useful fields of latitude and longitude geolocation grids from the WRF model. The original version is available upon request.
