Resolution No.21 (1967): Effort on airglow observations
The IAGA recommends that increased effort be made on the following observational programs:
- photometric detection of the 5200 Angstrom atomic nitrogen emission,
- determination of rapid temperature variations from Doppler broadening of omission lines,
- rocket-borne determinations of altitude profiles of airglow emission,
- twilight measurements of atomic helium fluorescence and ionised nitrogen scattering.
