Abstract:The SEBAL (surface energy balance algorithm for land) model provides an efficient tool for estimating the spatial distribution of evapotranspiration,and performs a simple adjustment procedure to calculate sensible heat flux using the wind speed data set from only one weather station.This paper proposes a simplified method to modify the traditional SEBAL model for calculating the 24-hour evapotranspiration () in the Haihe Basin with data from 34 weather stations.We interpolated the wind speeds using the inve...
Keywords:evapotranspiration  SEBAL model  MODIS  remote sensing  sensible heat flux  Haihe Basin
