Radiation Balance 2
Radiation Balance 2 : Also: Negative Radiation Balance, Positive Radiation Balance, Radiational Cooling. Sum of all the radiation heat inputs and losses at a surface (e.g., a snow surface). For snow this includes incoming solar radiation, outgoing long-wave (infra-red) radiation from the snow into a clear sky, and sometimes other factors as well. When the snow surface loses heat by infra-red radiation faster than it gains heat the condition is sometimes called a negative radiation balance, and the result is called radiational cooling. When it gains more heat than it loses it is then called a positive radiation balance
