2 METHODS FOR SATELLITE MEASURING OF OUTGOING RADIATION FLUXES

Measurements of outgoing radiation fluxes with spaceborne scanning nar row and nonscanning wide field-of-vision radiometers are considered. T he problem of data processing is discussed. Capacities of both methods are compared. Outgoing radiation fluxes are measured within short-wav e (SW) and long-wave (LW) ranges using spaceborne scanning and nonscan ning sensors whose field-of-vision is oriented to the nadir. Both type s of sensors yield a great deal of information (see e.g [1-3]). Effort s to interprete the obtained data have been made since early 60s [2, 4 -10, 12]. Evolution of the equipment for satellite measurements of com ponents of the Earth radiation balance (ERB) is in progress. In this c onnection it is interesting to compare methods employed to measure out going radiation by scanning and nonscanning spaceborne sensors.
