Helium-cooled balloon-borne infrared experiment for measurements of stratospheric trace gas emissions
Abstract:
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.

Noble Gases
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they were assumed to be nonreactive since they have filled valence shells. In 1962, Dr. Neil Bartlett at the University of British Columbia proved this assumption to be false.
