Rocket-borne measurements of atmospheric infrared emissions by spectrometric techniques

As part of the MAP/WINE Campaign 1983/84 a liquid helium cooled infrared grating spectrometer measured night zenith radiances of CO 2, O 3, and H 2O in the mesosphere and lower thermosphere. From a comparison of the measured spectral radiances with results from LTE radiative transfer calculations atmospheric temperatures and concentration profiles of H 2O and O 3 were determined, showing some interesting features. The ozone densities obtained appear to contradict model predictions based upon the assumption that ozone is in photochemical equilibrium at mesospheric heights. Since the ozone density distribution shows quite similar structures as the vertical wind profile, transport effects seem to play a major role in the mesospheric ozone formation.
