Western North American Climate Data from the Pacific Northwest Climate Change Vulnerability Assessment

ClimateWNA was used to downscale historical data and future climate projections to a 1-km 2 grid. ClimateWNA is a program that generates both directly calculated and derived climate variables for specific locations across western North America (Wang et al. 2012) using Parameter-elevation Regressions on Independent Slopes Model (PRISM). We generated annual, seasonal and monthly climate data for the period 1961 to 1990. For future climate projections, we used the SRES A2 greenhouse-gas emissions scenario from the IPCC Fourth Assessment Report. We generated five sets of future climate projections averaged for the time period 2070-2099: BCCR BCM2.0, CCCMA CGCM3, CSIRO MK 3.0, INMCM 3.0, MIROC3.2 MEDRES. Downloads:...

Pacific Climate Impacts Consortium ClimateWNA

ClimateWNA: A program to generate high-resolution climate data for climate change studies and applications in western North America Overview ClimateWNA extracts and downscales PRISM (Daly et al. 2002) monthly data (2.5 x 2.5 arcmin) for the reference period (1961-1990), and calculates seasonal and annual climate variables for specific locations based on latitude, longitude and elevation (optional) for western North America, shown in the map on the right. This program also downscales and integrates historical (1901-2011) (Mitchell and Jones 2005 for 1901-2009) and future climate data (2020s, 2050s and 2080s) generated by various global circulation models. The output includes both directly calculated and derived...
