Abstract

The SEBS model (The Surface Energy Balance System) based on land surface energy balance equation is used to estimate sensible heat flux and latent heat flux using remotely sensed data. In this paper, The SEBS model is validated with two sets of data collected in two field experiment on winter-wheat field in Shunyi county of Beijing (116° 26′ E-117° E; 40° N-40° 21′ N)and on bare soil in Changping county of Beijing (116° 26′ E 116° 28′ E; 40° 10′ N-40° 12′ N),China.Sensible and latent heat flux measured by eddy correlation method are compared with these SEBS estimates. The results show:(1) Diurnal variant of Sensible and latent heat flux estimated by SEBS basically agreed with the measured by eddy correlation method both on winter-wheat field and on bare soil, but the performance on winter-wheat field is better than on bare soil, the performance of sensible flux is better than that of latent flux. (2) Both on winter-wheat field and on bare soil, the precision of sensible heat flux estimated by SEBS is higher than that of latent heat flux, while the SEBS model performs better on winter-wheat field than on bare soil. (3) The sensitivity of SEBS to every parameter is different. The SEBS model is most sensitive to the available energy, up to 0.3, while it is more sensitive to surface-air temperature difference and aerodynamic resistance, up to 0.1 and 0.09 respectively.
