[1] The amount of solar irradiance reaching the surface is a key parameter in the hydrological and energy cycles of the Earth’s climate. We analyze 20th Century simulations using nine state-of-the-art climate models and show that all models estimate a global annual mean reduction in downward surface solar radiation of 1–4 W/m at the same time that the globe warms by 0.4–0.7 C. In single forcing...

[1] Model results and observations both indicate warming of the world ocean from 1955 to 2003. Forced by reanalysis data, the model also shows that the warming of the arctic ice–ocean system is faster than the global average since the 1960s; there is a small but widespread increase in heat content of the Arctic Ocean’s waters and a larger increase of latent heat embodied in the ocean’s decreasi...

Surface downward longwave radiation (SDLR) is a major component of the energy budget. Although studies have reported spatiotemporal variations SDLR in China, coverage situ measurements used always limited. In this study, gradient boosting regression tree (GBRT) was developed to reconstruct based on air temperature (Ta), relative humidity (RH), and shortwave (DSR). Ground collected at Baseline R...

This study investigates the extent to which assimilating high-resolution remotely sensed cloud cover into the Regional Atmospheric Modeling System (RAMS) provides an improved regional diagnosis of downward shortand longwave surface radiation fluxes and precipitation. An automatic procedure was developed to derive highresolution (4 km 3 4 km) fields of fractional cloud cover from visible band Ge...

Abstract Downwelling longwave radiation (DLR) driven by the atmospheric and cloud conditions in troposphere is suggested to be a dominant factor determine summertime net surface energy budget over Arctic Ocean thus plays key role shape September sea ice. We use reanalyses self-organizing map (SOM) method distinguish CMIP6 model performance replicating observed strong atmosphere-DLR connection. ...

the main driving force of the earth atmospheric system is solar radiation. radiation flux determines the surface temperature and impacts life on the earth through photosynthesis. a quantitative knowledge of the earth radiation field is important to evaluate the atmosphere–surface interactions and the global hydrological cycle. various atmospheric radiative transfer models have been proposed in ...
