The European Arctic Stratospheric Ozone Experiment is a European Commission (EC) measurement campaign undertaken in the Northern Hemisphere winter of 1991-92 to study ozone chemistry and dynamics. This dataset contains measurements of HNO3, CLO, HCL, air temperature and air pressure during the Arctic winter period of 1991/1992. The experiment provides spectrally resolved molecular line profiles that allow the retrieval of vertical volume-mixing-ratio (VMR) distributions. Altitude information can be extracted from the pressure broadening of the emission feature that dominates the line shape at altitudes approximately below 60 km.
