Downward solar radiation flux
WebDec 1, 2024 · Abstract Downward surface solar radiation (SSR) is a crucial component of the global energy balance, affecting temperature and the hydrological cycle profoundly, and it provides crucial information about climate change. Many studies have examined SSR trends; however, they have often concentrated on specific regions due to limited spatial … WebAug 4, 2024 · Shortwave solar radiation is an important component of the surface energy balance and provides the principal source of energy for terrestrial ecosystems.

The net or resultant value of the upward and downward longwave and shortwave radiative fluxes through a plane at the earth-atmosphere interface; a component of the surface energy budget. Webflux and spectra at any time at any point of the Martian surface. With this goal in mind, a new model for the radiation environment to be found on the planet Mars due to Galactic Cosmic Rays (GCR) has been devel-oped. Solar modulated primary particles [5] rescaled for Mars conditions are transported within the Martian
WebRadiation reflected from the earth's surface can be re-reflected back, and so surface albedo can influence the downward flux. Thus, BOA solar radiation is much less than that at TOA, and is commonly divided into two fluxes: direct radiation coming from a 2.5–5 ° angle centred in the direction of the sun, and diffuse radiation arriving from ...
