SAGE I Aerosol O3 NO2 Binary version 1

The Stratospheric Aerosol and Gas Experiment I (SAGE I) was launched February 18, 1979, aboard the Applications Explorer Mission-B (AEM-B) satellite. SAGE I was a sun photometer that used the solar occultation technique to measure aerosols and important stratospheric gases in the atmosphere. SAGE I collected valuable data for nearly three years until the power system on the satellite failed. SAGE I is a predecessor to the very successful SAGE II/III Missions. The data set here are the SAGE I measured vertical profiles of stratospheric multi-wavelength aerosol extinction coefficient and the concentration of ozone and nitrogen dioxide.
