Derivation of actual evapotranspiration in the Senegalese Sahel, using NOAA-AVHRR data during the 1987 growing season

Remote Sensing of Environment 46(2): 164-172

Derivation of actual evapotranspiration in the Senegalese Sahel, using NOAA-AVHRR data during the 1987 growing season

The actual evapotranspiration from one test site in the northern part of Senegal was calculated using a combination of NOAA-AVHRR data and meteorological data. AVHRR data were calibrated and corrected for the influence of the atmosphere. The relationship ET - RN = ab(Ts - Ta) was established on the basis of in situ measurements of fluxes during a field campaign September-October 1988. The flux measurements are presented, and the influence of surface roughness on the relationship is analyzed. A simple method for time integration of actual evapotranspiration between days with satellite data is presented.
