Evaluation of SEBS-estimated evapotranspiration using a large aperture scintillometer data for a complex underlying surface

This study firstly analyses the spatial representation of LAS (Large Aperture Scintillometer)-observed heat fluxes for a complex surface; and then evaluates the performance of SEBS model applied to a complex surface in comparison with in situ measurements. The results showed that LAS observation is indeed more stable than EC measurements even for complex surfaces, and the sensible heat flux from LAS is less than that from EC observations because of some land types with more evapotranspiration included into LAS footprint. SEBS overestimated latent heat flux at QYZ station in southern China because of the underestimation of H, but SEBS-estimated turbulent fluxes are more consistent with the LAS measurement.
