Abstract
AN article by Kaplan1 suggested a method of obtaining indirectly the temperature profile of the atmosphere by measuring from a satellite the radiances at several wavelengths in the 15-µ band of carbon dioxide. To test the practical application of this proposal the U.S. Weather Bureau has developed a grating spectrometer2 with fixed exit slits and detectors to measure simultaneously the radiances in 5 cm−1 intervals centred at 669, 677.5, 691, 697, 703 and 709 cm−1 and a 7 cm−1 interval centred at 899 cm−1.
