Stratospheric ozone measurements from the 1985 MAP/GLOBUS NOx campaign

Abstract

Nine experiments obtained stratospheric ozone measurements during the fall 1985 Middle Atmosphere Program (MAP) Global Budget of Stratospheric Trace Constituents (GLOBUS) NOx campaign. Measurements are grouped into four sets from four air masses and compared. Agreement between individual experiments and weighted mean profiles is generally within 10% and within absolute accuracies. Dobson Umkehr values in layer 5 differ by more than absolute accuracies from weighted mean profiles. Brewer sonde values for one data set are outside absolute accuracies near the ozone peak. Solar UV occultation measurements are 30–35% less than the weighted mean profile and outside absolute accuracies. Measurements from the Exospheric Satellite (EXOS‐C) backscattered ultraviolet (BUV) experiment, not previously compared with other techniques, agree within 10–15% of weighted mean profiles. Results of the campaign are generally consistent with those of four previous intercomparison campaigns.
