Helium-cooled balloon-borne infrared experiment for measurements of stratospheric trace gas emissions.
A helium-cooled IR spectrometer with a diffraction-limited telescope was launched on 23 Sept. 1983 from Aire-sur-l'Adour (France) as part of the MAP/Globus 1983 campaign. The float altitude of the balloon was 38 km. Limb scan measurements of atmospheric emissions were taken in the 5.5-19-microm wavelength region. The measurements were performed ~1 h before sunrise. From several spectral features volume mixing ratios of NO(2), H(2)O, CH(4), HNO(3), O(3), and N(2)O were derived.
