radiation balance

Earth's radiation balance is the equation of the incoming and outgoing thermal radiation.The incoming solar radiation is short wave, therefore the equation below is called the short wave radiation balance Qs:Qs = G - R = D + H - R or depending on the albedo (back-reflection to space): = G (1 - a)G = global radiationD = direct radiationH = diffuse radiationR = reflected portion of global radiation (ca. 4%)a = albedo
