Abstract: Radiances emitted from the atmosphere near 669.3 cm?1 in the center of the 15-µm CO2 band were measured from the Nimbus 3 satellite. Changes in observed radiance correspond to weighted temperature changes of the upper 100 ...

Abstract: The radiances in the CO2 band centered at 669.3 cm?1 (15 ?), measured by the satellite infrared spectrometer on Nimbus III, are examined. These radiances are a measure of a weighted mean temperature of approximately the ...

Abstract: Three spectrometers and associated experiments are described. The work reviewed comprises the early experimental phases of a program to develop a satellite infrared spectrometer capable of making radiometric measurements ...
