8.5. Summary
This chapter discussed methods for estimating the surface longwave radiation budget, and it consisted of three major sections. The first section presented methods for estimating the surface downward longwave radiation, the second section discussed methods for estimating the surface upwelling longwave radiation, and the third section presented methods for estimating the surface net longwave radiation.
In recent decades, many studies have been devoted to the estimation of the surface downward longwave radiation. Three categories of surface downward longwave radiation budget methods have been summarized: (1) profile-based methods, (2) hybrid methods, and (3) meteorological parameter–based methods. Profile-based methods and hybrid ...
