This dataset depicts average annual evapotranspiration for the globe on
a 0.5 X 0.5 degree global grid. Evapotranspiration field represents a
long term annual average (mm/yr) computed from monthly modeled
evapotranspiration for years 1950-2000. Annual evapotranspiration -
long-term annual average evapotranspiration (mm/yr) computed from
monthly modeled evapotranspiration using Shuttleworth and Wallace (1985)
PET estimates (Vorosmarty et al, 1998) and limited by modeled soil moisture.
The data is in ESRI GRID raster format.
