| 英文摘要 | As well known, the methods of remote sensing and bowen ratio for retrieving surface flux are based on energy balance closure; however, in most cases, surface energy observed in experiment is lack of closure. there are two main causes for this: one is from the errors of the observation devices and the differences of their observational scale; the other lies in the effect of horizontal advection on the surface flux measurement. therefore, it is very important to estimate the effects of horizontal advection quantitatively. based on the local advection theory and the surface experiment, a model has been proposed for correcting the effect of horizontal advection on surface flux measurement, in which the relationship between the fetch of the measurement and pixel size for remote sensed data was considered. by means of numerical simulations, the sensitivities of the main parameters in the model and the scaling problems of horizontal advection were analyzed. at last, by using the observational data acquired in agricultural field with relatively homogeneous surface, the model was validated. |
