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 ...

The article considers the results of an estimation shortwave radiation flux at surface in Morocco from 2021-2050. Average monthly values coming to underlying (Surface Downwelling Shortwave Radiation, RSDS), calculated using 11 regional climate models CORDEX-Africa project, were used as input data. model calculation was performed assuming a greenhouse gas concentration scenario RCP4.5. aim work ...

To evaluate and improve the treatment of clouds and radiation by the climate models of the National Center for Atmospheric Research (NCAR), simulations by the NCAR Community Climate Model version 3 (CCM3), as well as the recently released Community Atmosphere Model version 2 (CAM2), are examined. The Rasch and Kristjánsson prognostic cloud condensate scheme, which is now the standard scheme for...

During the Line Islands Experiment in spring 1967, surface shortwave and net radiation was continuously recorded a t Palmyra, and Suomi-Kuhn infrared radiationsondes were released daily at the islands of Palmyra, (5’53’ N., 162’05’ W.) and Christmas (1’59’ N., 157’22’ W.) as part of an extensive surface and upper air observation program. Data are evaluated in terms of the diurnal march of the s...

The Net Surface Shortwave Radiation (NSSR) is of primary interest in climate research because it controls the total energy exchange between the atmosphere and the land/ocean surface. The conventional methods for estimating NSSR rely on broadband satellite data such as Earth Radiation Budget Experiment (ERBE) wide-field-of-view planetary albedo. The spatial resolution of the current ERBE satelli...

The downwelling shortwave irradiance typically consists of both a direct component of radiation from the sun, and a diffuse component of scattered sunlight from the sky. Significant offsets can occur in downwelling shortwave irradiance measurements made from moving platforms due to the tilt of the instruments from horizontal which changes the angular orientation of the direct component of sunli...
