A new Dobson Umkehr ozone profile retrieval method optimising information content and resolution

The standard Dobson Umkehr methodology to retrieve coarse-resolution ozone profiles used by the National Oceanographic and Atmospheric Administration uses designated solar zenith angles (SZAs). However, some information may be lost if measurements lie outside the designated SZA range (between 60 and 90), or do not conform to the fitting technique. Also, while Umkehr measurements can be taken us...

Sensitivity of Dobson and Brewer Umkehr ozone profile retrievals to ozone cross-sections and stray light effects

Remote sounding methods are used to derive ozone profile and column information from various groundbased and satellite measurements. Vertical ozone profiles measured in Dobson units (DU) are currently retrieved based on laboratory measurements of the ozone absorption crosssection spectrum between 270 and 400 nm published in 1985 by Bass and Paur (BP). Recently, the US National Aeronautics and S...

Aerosol Effect on Umkehr Ozone Profiles using SAGE II Measurements

This study examines 1211 cases of coincident ozone profiles derived from 1164 Umkehrs and 928 SAGE II profiles within 1000 km and 12 hours between October 1984 and April 1989 to study the stratospheric-aerosol effect on Umkehr ozone profiles. Because of the close correspondence of stratospheric aerosol optical depth at the SAGE II-measured 0.525 micron wavelength and the extrapolated 0.32 Umkeh...

A comparison of UV intensities calculated by spherical- atmosphere radiation transfer codes: Application to the aerosol corrections

Various spherical radiative transfer (SRT) computer codes that model ultraviolet (UV) sky intensities incident at the Earth’s surface are compared for clear-sky (Rayleigh scattering and ozone absorption) and hazy-sky (stratospheric volcanic aerosol, Rayleigh scattering, and ozone absorption) atmospheric conditions. Calculated sky intensities using Dave vector (pseudospherical), Dave scalar (pse...

Uncertainties in upper stratospheric ozone trends from 1979 to 1996

The time series of differences in coincident measurements of ozone by Stratospheric Aerosol and Gas Experiment (SAGE) and by Solar Backscattered Ultraviolet (SBUV), SBUV/2, Umkehr and Microwave Limb Sounder (MLS) are analyzed, and the slopes in the differences are calculated. SAGE ozone measurements are also compared against those by HALOE. The purpose of these comparisons is to look for statis...
