Definitions for "Radiation balance"
The difference between the absorbed solar radiation and the net infrared radiation. Experimental data show that radiation from the earth's natural surfaces is rather close to the radiation from a black body at the corresponding temperature; the ratio of the observed values of radiation to black body radiation is generally 0.90-1.0.
the Earths energy balance between the incoming solar energy and outgoing energy radiated out as longwave radiation
The resultant flux of the solar and terrestrial radiation through a horizontal surface. It is considered positive in the flux downwards exceeds that upwards. It is also termed 'net radiation'.
Keywords:  algebraic, radiant, snow, inputs, sum
Algebraic sum of all the radiant heat inputs and losses at a surface (e.g., a snow surface).
