Table summary
This table displays the results of Evapotranspiration and potential evapotranspiration change. The information is grouped by Ecoprovince (appearing as row headers), Code, Annual evapotranspiration change, 1979 to 2016, Season of largest evapotranspiration change, 1979 to 2016, Evapotranspiration change for season of largest change, 1979 to 2016, Annual potential evapotranspiration change, 1979 to 2016, Season of largest potential evapotranspiration change, 1979 to 2016 and Potential evapotranspiration change for season of largest change, 1979 to 2016, calculated using mm and season units of measure (appearing as column headers).

Trends in evapotranspiration and potential evapotranspiration are reported for linear trends to the 90% confidence interval or above. Caution should be used when analyzing trends in the northern Arctic islands and along the Yukon–Alaska border because of lower climate station densities.
