Sensible heat flux estimation using Surface Energy Balance System (SEBS), modis products, and NCEP reanalysis data

This paper used the Surface Energy Balance System (SEBS) to estimate the regional sensible heat flux, fully using the advantages of temporal and spatial resolutions of MODIS data and the height of the Planetary Boundary Layer of NCEP reanalysis data. In addition, a new approach which deriving the value of roughness length of momentum transfer was being used in this paper to improve the accuracy of calculation. Based on the LAS measurements at Arou site and sensible heat predictions data provided by NCEP, regional sensible heat flux in Arou area estimated by MODIS data and NCEP data was validated. The retrieval and the verification of the regional sensible heat flux in Arou area showed that the calculated results of the remote sensing model were in good agreement with LAS measurements in situ and NCEP sensible heat products. The results demonstrated that running SEBS model with NCEP meteorological data was feasible.
