SAGE II instrument: Stratospheric Aerosol and Gas Experiment II
The SAGE II instrument was developed by NASA to provide the scientific community with a global, long-term description of the distribution of aerosols, ozone, water vapour and NO2. It thus provides a unique and crucial database for improving our understanding of global, seasonal and inter-annual climate variability and, in particular, trends in stratospheric ozone.
Two types of SAGE II data are available from Ether dating from 24/10/1984 on; data related to NASA's official data products: level 2 vertical profiles and ancillary data for temperature, pressure, density and coordinates.
Two types of data are available on Ether from 1984-10-24, data from the official NASA production: vertical profiles (level 2) and correlative data of temperature, pressure, density and coordinates.

Two types of data are available: vertical profiles (level 2) named SAGEII ( O3, H2O, NO2, density, aerosols and coordinates) and ancilary data as temperature, pressure, density and coordinates named SAGEII.CORR .
