Abstract
Apparatus for remotely sensing changes in the spatial temperature profile of a column of atmospheric air includes (a) collecting means for receiving the thermal radiation from a column of atmospheric air, and for directing it to intensity sensing means; (b) sensing means with a rotatably mounted interference bandpass filter together with means for rotating the filter for sequentially tuning to and sensing the intensity in said column of atmospheric air of at least two spectral regions in the 4.17 to 4.2 .mu.m region of the CO.sub.2 spectral emission band; and (c) means for detecting temporal changes in the relative intensity of the spectral regions.
