The Cryogenic Limb Array Etalon Spectrometer (CLAES) measured vertical profiles of temperature and concentrations of ozone, methane, water vapour, nitrogen oxides, and other important species, including CFCs, in the stratosphere. CLAES also maps the horizontal and vertical distributions of aerosols in the stratosphere. These measurements are analysed to better understand the photochemical, radiative, and dynamical processes taking place in the ozone layer. This is the third version of CLAES data to be put into the public domain on the NASA-GDAAC. The dataset contains O3, ClONO2, F11, HNO3, N2O, N2O5, NO2, aerosols and temperature measurements. Data are level 3A product (gridded in time and latitude along the satellite track) between 80N - 80S, 10-60 Km, October 1991 - May 1993. This dataset is public.
