WebA radiometer which is to measure the total terrestrial radiation upwards and/or downwards must exchange radiation freely with all parts of the appro- priate hemisphere. A n uncovered black receiver will do this, but unfortunately it is subject to other forms of heat exchange, chiefly convection, which falsify the readings. WebJan 1, 1985 · Albedo is defined as the ratio of reflected to incident electromagnetic radiation in the total solar spectrum or in a certain wavelength interval. Reflectivity refers to a specific wavelength and direction. The term “albedo” is used rather freely in the literature. No attempt will be made to define it as appropriate in each reviewed case. global tykon construction
