30-year Average Potential Evapotranspiration (mm)

Water demand is usually measured by evapotranspiration: the amount of water that would be evaporated and transpired by plants. Potential Evapotranspiration (PET) is the demand or maximum amount of evaporation that would occur if sufficient water were available (from precipitation and soil moisture). Priestly-Taylor equations were used to estimate daily PET.

These values are calculated across Canada using historical climate station data from ECCC with the Versatile Soil Moisture Budget model (Baier and Robertson, 1996 and Baier et al., 2000).
