Middle infrared emission studies in the upper atmosphere by rocket techniques
Abstract
A liquid helium cooled infrared twin grating spectrometer for use on sounding rockets was built. It was successfully flown three times on Skylark rockets from Esrange, Sweden. The experiments covered the midinfrared spectral range of 2.5 to 17 microns with a resolving power of 150 during the first two flights and 85 during the last flight. The far infrared regime between 50 and 100 microns was scanned with a resolution of 15. The instruments yielded zenith spectra and zenith intensity profiles of the vibration-rotation band emissions of CO2 at 15 microns and of O3 at 9.6 microns. In the far infrared the pure rotational spectrum of water vapor was measured.
