WebReflected Shortwave radiation refers to the total of all the shortwave electromagnetic energy, or sunlight at wavelengths ranging from 0.3 to 5 micrometers, that escapes from the top of the Earths' atmosphere back into space. About 30% of the incoming solar energy is … WebIncoming energy reaches the Earth from the Sun. Outgoing energy flows from Earth back out to space. "When Earth absorbs sunlight, it heats up. The heat, or "outgoing longwave radiation," radiates back into space. Satellites measure this radiation as it leaves the top of Earth's atmosphere. The hotter a place is, the more energy it radiates." WebAs for solar radiation, these changes in longwave radiation vary from city to city. The net result of lower downwelling shortwave, and increased longwave, radiation fluxes is little change in the total incoming all-wave radiation (Oke, 1988; Cleugh, 1995a; Arnfield, 2003). shania fox
