註釋The total thermal radiative power exchange at the atmosphere-earth interface and within the atmosphere is a direct measure of energy (power) available to drive the "heat engine" that circulates the atmosphere. In view of this, its implication in meteorological analysis is vital for the approach to a full solution of atmospheric circulation. The lack of a sufficient number of surface and upper air thermal radiation soundings prompted the development of the radiometersonde, a low-cost balloon-borne radiometer. This instrument, flown as part of a standard radiosonde ascent, separately measure upward, downward, and net thermal radiation. A summary and analysis of 400 out of 2,000 Antarctic radiometersonde ascents gives 40,000 individual measurements of net, upward, and downward thermal radiation. The average stratospheric net outward radiation for Pole Station in the dark season is 0.145 ly/min, and that for Byrd Station is 0.210 ly/min. The standard deviation about the average for Pole Station is 0.039, and for Byrd Station is 0.005 ly/min
