Species profiles (SPEC files) and revision information (INDEX) from the Stratospheric Aerosol and Gas Experiment II (SAGE II), an instrument on board the Earth Radiation Budget Satellite (ERBS) which used the solar occultation technique to measure global profiles of aerosol extinction, temperature, ozone, nitrogen dioxide and water vapour in the stratosphere and upper troposphere. Version 1 of the data consist of monthly mean global image maps and associated gridded data for the period 1985-1993. Version 6.1 contains INDEX and SPEC files for the period October 1984 to July 2000 and was superseded by version 6.2, available for the period October 1984 to August 2005. Access to this dataset is partially restricted.

Species information includes aerosol extinction profiles at 1020, 525, 453, and 385 nanometers, number density profiles of ozone and nitrogen dioxide, plus molecular density and mixing ratio profiles of water vapour. It also includes aerosol surface area density and effective radius profiles, and retrieved molecular density for the middle atmosphere (40-75 km). All profiles are at 0.5-km vertical resolution. These products are nearly global in coverage, with data spanning from 80 North to 80 South.
