More such measurements and networks for measurements are needed, particularly in developing countries where use of technology to reduce vulnerability to climate variability is severely limited.
The central role of the surface energy balance in agricultural climatology calls for accurate methods of evaluating fluxes of heat, momentum, moisture, and trace gases from crop, soil, and forest surfaces. Unfortunately, this is not an easy task for heterogeneous surfaces typically encountered in agricultural applications. Estimates of surface fluxes can be made by drag coefficient formulations and gradient diffusion estimates or by eddy correlation methods.
