During winter 1991/92 DOAS (Differential Optical Absorption Spectroscopy) measurements were performed from a C130 Transall aircraft within the frame-work of the EASOE (European Arctic Stratospheric Ozone Experiment) campaign. The campaign extended from Dec. 1991 until March 1992 with a series of flights in the Arctic (60¿W to 60¿E, 85¿N to 48¿N). Two spectrometers were operated on the aircraft: an UV-instrument (see Brandtjen et al., this issue) and a DOAS-vis instrument to detect O3, O4, NO2, and NO3 in the visible band (363 nm--680 nm). The DOAS-vis ozone measurements were largely influenced by the presence of the Mt. Pinatubo aerosol cloud. A correction of the data by actual Mie-profiles is described. A NO2 depletion with minimum values of 2.3*1014/cm2 in Jan. 92 was observed. Occasionally, OClO could also be detected. ¿ American Geophysical Union 1994
