Description

The primary purposes of this project were to revise the 1981 ecoregion classification of Alberta, update the climatic characterization, and develop an ecodistrict classification at a 1:1 000 000 map scale. Revision of the classification and mapping was based on both new data and a reassessment of pre-1980 information. Characterization of the climate associated with each ecoregion was based on monthly data from 1st January 1979 to 31 st August 1989. These data included eight primary monthly variables: mean, mean minimum, mean maximum, absolute minimum and maximum temperature; total monthly precipitation; number of days with measurable precipitation; and number of days with temperatures equal to or less than O°C. Derived variables included potential evapotranspiration deficits and growing degree days. A total of 211 recording stations were analyzed .
