Sentences with phrase «fraction of incoming radiation»

Eventually, as the snow turns into glacier ice, the reflected fraction of incoming radiation drops to as low as one half or less.

Not exact matches

If the surface plus atmosphere together acts as a gray body at 288 K with e = 0.61, then only 61 % of incoming solar radiation at thermal infrared wavelengths (a small fraction of the total) will be absorbed.

Let the top layer be a gray body with emissivity e and suppose it also absorbs a fraction f of the incoming solar radiation.

Suppose further that a fraction «a» of the incoming shortwave radiation is absorbed in the atmosphere (with the remainder being absorbed by the ground).

Five to six times as much incoming solar radiation is reflected back to space from clouds as from the Earth's surface (of which only a fraction is from snow or ice).

An atmosphere that is perfectly transparent to incoming and outgoing radiation can not radiate and all its heat content comes from conduction from the surface and is transported through the atmosphere solely by convection with no loss of energy to space except for the tiny fraction of atoms at the top of the atmosphere that exceed escape velocity.
