temperature covariance
1.This paper presents the results of one year (2004) continuous measurements of surfacefluxes above stipa krylovii steppe in Inner Mongolia using eddy covariance method (EC),moreover, variational technique(VT) is used to estimate surface fluxes of sensible and latentheats in terms of the gradient observations including wind speed, air temperature andhumidity, respectively, at two heights (2m and 4m) by microclimatic gradient system, andcompared with EC and Bowen ratio energy balance methods (BREB).
