The authors report on further analysis of a stratospheric cooling event observed by CHEOPS 3 during February 4-6, 1990 over Scandinavia. The CHEOPS 3 observational program provided a large set of data regarding atmospheric conditions in the Arctic polar region which are of use in addressing the question of ozone depletion in the northern hemisphere. A large temperature excursion was observed in this period by the CHEOPS data, and the authors have applied a new inversion to TOVS observations of this same period to attempt to confirm this observation. Such a large excursion would allow the formation of polar stratospheric clouds. They were able to model the general cooling pattern seen by the CHEOPS 3 observations, but not the large temperature dip, and offer an alternative explanation of the accompanying dip in ozone column densities observed over Europe at this time.
