The impact of local advection on the accuracy of surface fluxes based on remote sensing

In this paper, the theoretical explanation of energy "unbalance" phenomena is presented and local advection experiments executed over a farmland are introduced. The results show that, (1) The influence of local advection depends on wind speed, wind direction, fetch and temperature difference between two adjacent fields or pixels. (2) Because there are uncertainty of heat fluxes obtained by some micrometeorological methods(mainly caused by advection and instruments precision) in some times, and the fluxes are often regarded as the calibrations of remote sensing fluxes, the accuracy of fluxes retrieved from remote sensing data will be affected
