Resolution No.21 (1967): Effort on airglow observations

The IAGA recommends that increased effort be made on the following observational programs:

  1. photometric detection of the 5200 Angstrom atomic nitrogen emission,
  2. determination of rapid temperature variations from Doppler broadening of omission lines,
  3. rocket-borne determinations of altitude profiles of airglow emission,
  4. twilight measurements of atomic helium fluorescence and ionised nitrogen scattering.
