Abstract: On calculating heat flux, latent flux and momentum flux, the errors of heat exchange coefficient cT, evaporation coefficient c E, and friction coefficient cv are brought about, owing to the different measure height of meteorological elements, respectively, which will affect the result to a certain extent, In the paper, a method of height correction is introduced in order to amend the coefficients. And, the method will improve the accuracy of calculation. The result shows the errors of coefficient corrected can reduce by a factor of 9% to 11%.
