abstract

  • Evapotranspiration was measured periodically from late June through mid‐August 1978 in Eriophorum vaginiatum tussock tundra near Eagle Creek, Alaska. The average evapotranspiration rates from tussock and intertussock areas were 0.8 mm d−1 and 1.3 mm d−1, respectively. Potential evaporation was calculated according to the Penman equation using microclimate data collected at the same time actual evapotranspiration was measured. Actual evapotranspiration was 0.56 ± 0.06 (X± SE, N = 10) of the potential evaporation from moss and 0.43 ± 0.08 (X± SE, N = 10) of the potential evaporation from E. vaginatum tussocks. Seventy three percent of the variability in the ratio of actual evapotranspiration to potential evaporation from tussocks was accounted for by linear regression on net radiation. Eighty nine percent of the variability in the same ratio for mosses was explained by linear regression on the vapor pressure deficit of the air and net radiation. Copyright © 1982, Wiley Blackwell.
