8.3. Surface net longwave radiation

Surface net longwave radiation (SNLR) is the difference between the surface downward and upwelling longwave radiation. SNLR is dominated by longwave radiation at night and at most times of the year in the polar regions. SNLR is an important part of radiant energy balance, and its accurate estimation is of great significance to weather forecast, climate simulation, and land surface process simulation results. This section will introduce the estimation of the SNLR under clear-sky conditions and the SNLR under cloudy conditions.

8.3.1. Estimation of surface net longwave radiation in clear sky

At present, there are two methods for estimating surface net longwave net radiation: one is the component mode. More ...
