Ground-based measurements of night-sky NIR and visible emissions were made at the Andenes, Norway, and Kiruna, Sweden, rocket launch sites during the Energy Budget Campaign of 1980. Optical measurements were made using visible and infrared photometers, a Michelson interometer and a grating spectrometer. The spectral range of the spectrometers was 0.85-1.7 microns. Photometer wavelength coverages were at 1.7 microns, 1.27, 6300 A, 5577 A, 5525 A and 3914 A. Emission intensities of OH, O2, N2(+) and O airglow and auroral species are presented. Correlations were observed between the O2(a1 delta-g) emission at 1.27 microns and the OH(8,5) emission at 1.3 microns, giving further evidence that the two species of the night airglow have an emission mechanism in common. Values of the roational temperatures of the OH airglow were derived which are indicative of the temporal history of the near-mesopause atmospheric temperature. Airglow intensities and temperatures are compared with indices of auroral zone geomagnetic activity and with key atmospheric measurements obtained in the campaign. Correlations were found with high significance levels. The trends in the observed mesopause temperature appear to be part of a general disturbance of the atmosphere due to planetary waves.
