Abstract

Evapotranspiration is one of the most significant components of the hydrologic budget. Satellite sensors that observe the earth from the space give a possibility to estimate evapotranspiration at a big scale. In this paper, Surface Energy Balance System (SEBS) has been utilized to estimate the surface fluxes over Hebei Plain in Northeastern China by using MODIS/TERRA images, in combination with meteorological data collected in meteorological stations distributed over the study area. The estimated daily evapotranspiration by SEBS in cloud free days are first compared with measurements by the large weighing lysimeter in Luancheng Agro-Ecosystem Station (LAES). The comparisons show that the estimated evapotranspiration from SEBS have a good agreement with the ground truth data. Based on the validation of the model, the spatial-temporal distributions of actual evapotranspiration were analyzed by combination of the up-to-date land cover map in Hebei Plain.
