Abstract
A Grille Spectrometer was operated on board Spacelab-1, launched on 28 November 1983 for a nine-day mission. Solar occultation absorption spectra that show ozone-specific absorption features have been taken in the infrared range between 1039.6 and 1081.3 cm-1, with a spectral resolution of about 0.055 cm-1. Northern as well as southern hemisphere locations have been covered. The determination of ozone vertical-concentration profiles from these spectra has required the development of an improved inversion program based on Mill's algorithm. The most important ameliorations are the more accurate treatment of the molecular-line parameters and the introduction of Fourier-filter techniques for minimizing the influence of noise that severely affects the ozone spectra. The resulting ozone vertical profiles, between about 25 and 65 km altitude, are discussed and compared with data taken at the same time and location by other instruments (e.g., SME). In the future, these results will be compared with data taken with the same instrument during the ATLAS-1 mission and with a slightly adapted version of the spectrometer onboard the Soviet space station MIR is order to detect global changes.
