Descripción
A PHASE-MODULATED Michelson interferometer1 and a helium cooled Rollin2 photoconductive far infrared detector, at the focus of a 35 cm aperture Cassegrain telescope, were flown at a height of 12.1 km from the Royal Aircraft Establishment, Farnborough, in a Comet 2E aircraft, on November 11, 12 and 16, 1971. The emission spectrum of the stratosphere was obtained in the wavenumber range from 36 cm-1 to 5 cm-1 (wavelengths 280 µm to 2 mm)3. Here we describe an analysis of a portion of this spectrum for features produced by sources outside the Earth's atmosphere.
