SEBAL Based Regional-scale Evapotranspiration Estimation: A Case Study in North
|
Abstract: The Surface Energy Balance Algorithm for Land (SEBAL) is applied in this paper to three Moderate-resolution Imaging Spectroradiometer (MODIS) scenes of 2004 and 2005 to retrieve the regional-scale evapotranspiration in North China Plain. Firstly a brief review is given to the SEBAL and necessary inputs. These inputs include surface albedo, vegetation indices, emissivity, temperature, roughness and incoming global radiation. Then these inputs are used to derive the daily evapotranspiration with emphasis on dry pixel and wet pixel selection using SEBAL. Finally, the regional evapotranspiration over North China Plain were analysis based a preliminary comparison performed between the derived actual evapotranspiration and limited in-situ point measurement data.
Keywords: Evapotranspiration, Remote Sensing, SEBAL
