This data is gathered from ClimateBC (version 5.03) and includes data related to precipitation and temperature for the period 1961 to 1990. This period of climate data is commonly referred to as the Climate Normals. Climate normals are derived from the arithmetic mean of weather measurements from weather station records over three consecutive decades.

ClimateBC utilizes historical weather station data and global circulation model regional predictions to project future seasonal and annual climate variables in BC, western North America and entire North America. The program extracts and downscales PRISM (Daly et al. 2008) and ANUSPLIN (Hutchinson 1991) generated monthly data (2.5 x 2.5 arcmin) for the reference period (1961-1990), and calculate seasonal and annual climate variables for specific locations based on latitude, longitude and elevation (optional). The program also downscales and integrates historical (1901-2012) (Mitchell and Jones 2005) and future climate data sets (2020s, 2050s and 2080s) generated by various global circulation models from IPCC AR5. The output includes both directly calculated and derived climate variables. There are 23 annual, 56 seasonal and 168 monthly climate variables. Methodologies are described in Wang et al. (2012).
