This is due to the high albedo on Venus (0.8): 80% of solar radiation is reflected to space … WebJan 1, 2024 · Radiation reflected from the Earth's surface can be rereflected 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 to 5° angle centered on the sun, and diffuse radiation from the rest of the sky hemisphere. WebRT @AnthonyFreda10: According to the same Royal Society report, the function of SRM is to, "...reduce the net incoming short-wave (ultra-violet and visible) solar radiation received, by deflecting sunlight, or by increasing the reflectivity (albedo) of the atmosphere, clouds or the Earth's surface." 13 Apr 2024 21:59:05 tomate zima
