Analysis and comparison of ozone MAPS obtained by TOMS and TOVS during the MAP/GLOBUS 1983 campaign

The Nimbus 7 Total Ozone Mapping Spectrometer (u.v.) and the NOAA 7 and NOAA 8 Tiros Operational Vertical Sounder (i.r.) data have been specially processed for the MAP/GLOBUS campaign (September 1983, over Europe). Comparison of the ozone results shows a general agreement but also some discrepancies due to clouds, emissivity of the surface and latitude effects. The variability of the ozone field, closely linked to geopotential height field, may have induced a great change in total ozone along the balloon flights, but fortunately trajectories tend to lie parallel to the total ozone contours so that the total ozone during each flight is nearly constant.
