Determination of soil heat flux in a tibetan short-grass prairie

Soil heat flux is examined using a new method considering soil thermal conduction and convection processes. Using this method, we determine that soil heat fluxes owing to soil thermal conduction and convection were significant for the Naqu site in the summer of 1998. Experimental analyses of the surface energy balance are given.
