Welcome to ClimateWNA

This is a mirror site for ClimateWNA at the Centre for Forest Conservation Genetics (CFCG) at the Department of Forest Sciences, University of British Columbia

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 maps below. This program also downscales and integrates historical (1901-2009) (Mitchell and Jones 2005;Mbogga et al. 2009) and future climate datasets (2020s, 2050s and 2080s) generated by various global circulation models. The output includes both directly calculated and derived climate variables. Methodologies are described in Wang et al. (2012).
