AB: Satellite measurements of ozone vertical profiles are critical for providing detection of changes in stratospheric ozone on a global scale. Recently, NASA Goddard Space Flight Center/Atmospheric Chemistry and Dynamics Branch has developed a new ozone profile algorithm (Version 8) for solar backscattered ultraviolet (SBUV) data with full multiple scattering, improved forward and inverse models, improved temperature and ozone climatology as well as better calibrations. These data (Nimbus 7, and NOAA's SBUV 2 series of NOAA-11, and NOAA-16) are compared with the external data from three Lidar (Mauna Loa, Table Mountain, Haute Provence), and six Sonde (Hohenpeissenburg, Payerne, Boulder, Wallops Island, Tateno, Hilo) stations and Stratospheric Aerosol and Gas Experiment II (SAGE II) for validating retrieved SBUV ozone profiles. This study shows how V8 SBUV data agree well with daily coincident external data, and also introduces a method to convert layer ozone differences into percent radiance differences for each SBUV wavelength using the Jacobian now included in each V8 SBUV data record.
