Remote sensing measurements of ozone in ultraviolet, visible and infrared domains performed in September 1983 by means of stratospheric balloons during the MAP/GLOBUS campaign in France are presented and discussed. Ozone concentrations deduced from planet and solar occultation measurements in the Huggins and Chappuis absorption bands are given with an uncertainty of ± 10%. The results obtained from absorption measurements in the Chappuis bands give systematically higher concentration values than those deduced from in situ techniques. Discrepancies of the order of 20% are found between 24 and 34 km altitude. They are larger below the ozone maximum and above 35 km. The analysis of the data shows an aerosol contribution in the measured optical depth in the Chappuis bands for altitude below 28 km, giving overestimated inferred ozone concentrations. Discrepancies at higher altitudes with in situ soundings are difficult to explain.
