Solar Radiation 1
Solar Radiation 1 :
(Meteor) Sunlight or sunshine. The energy, ranging from long infrared to short ultraviolet, reaching the earth from the sun. The atmosphere strongly absorbs the energy at the extremes of this range. Note: The solar constant is defined as the quantity of energy that falls in a unit time on a unit area normal to the sun's rays at the edge of the earth's atmosphere. The mean value is 1. 36 • 106 ergs/cm2-sec, 1. 938 cal/cm2-min, or 1. 8 hp/m2. A third to a half of this energy is reflected back into space or scattered by the atmosphere
