Abstract

Ozone profiles are derived from backscattered radiances in the ultraviolet spectra (290-340 nm) measured by the nadir-viewing Global Ozone Monitoring Experiment using optimal estimation. Tropospheric O₃ is directly retrieved with the tropopause as one of the retrieval levels. To optimize the retrieval and improve the fitting precision needed for tropospheric O ₃, we perform extensive wavelength and radiometric calibrations and improve forward model inputs. Retrieved O₃ profiles and tropospheric O₃ agree well with coincident ozonesonde measurements, and the integrated total O₃ agrees very well with Earth Probe TOMS and Dobson/Brewer total O₃. The global distribution of tropospheric O₃ clearly shows the influences of biomass burning, convection, and air pollution, and is generally consistent wiht our current understanding.
