“…The current SCIAMACHY limb retrieval (V2.9) uses combined spectral information from the UV and visible spectral ranges to obtain vertical profiles of ozone (Flittner et al, 2000;Rohen et al, 2006). As the first step, the limb spectral radiances are integrated in ±1 nm intervals around the central points.…”

Abstract. In this paper, the latest SCIAMACHY limb ozone scientific vertical profiles, namely the current V2.9 and the upcoming V3.0, are extensively compared with ozonesonde data from the World Ozone and Ultraviolet Radiation Data Centre (WOUDC) database. The comparisons are made on a global scale from 2003 to 2011, involving 61 sonde stations. The retrieval processors used to generate V2.9 and V3.0 data sets are briefly introduced. The comparisons are discussed in terms of vertical profiles and stratospheric partial columns. Our results indicate that the V2.9 ozone profile data between 20 and 30 km are in good agreement with ground-based measurements, with less than 5 % relative differences in the latitude range of 90 • S-40 • N (with the exception of the tropical Pacific region, where an overestimation of more than 10 % is observed), which corresponds to less than 5 DU partial-column differences. In the tropics the differences are within 3 %. However, this data set shows a significant underestimation northwards of 40 • N (up to ∼ 15 %). The newly developed V3.0 data set reduces this bias to below 10 % while maintaining a good agreement southwards of 40 • N with slightly increased relative differences of up to 5 % in the tropics.

“…For futher details of the retrieval methodology and algorithm we refer to previous publications Rohen, 2006;Rohen et al, 2006). However, the reached sensitivity of the retrieval to ozone is proposed to be between about 35 and 60 km, sometimes 65 km.…”

“…It is based on the fitting of measured and modeled limb radiance profiles at discrete wavelengths. The inversion technique applied to SME measurements, up to now the only successful ozone retrieval from satellite-borne limb limb scatter measurements in the UV-B, exploits radiances at 265 and 296.4 nm (Rusch et al, 1983); ozone profile retrievals at wavelengths in the HART-LEY bands from SOLSE observations (McPeters et al, 2000) have also been done using this method, but had difficulties due to a low signal-to-noise ratio. For their attempt of a routine profile retrieval, radiances at eleven discrete wavelengths between 300 and 355 nm have been used (McPeters et al, 2000).…”

“…For their attempt of a routine profile retrieval, radiances at eleven discrete wavelengths between 300 and 355 nm have been used (McPeters et al, 2000). For this retrieval, the maximum of ozone absorption cross section in the HARTLEY bands (around 255 nm) (Wayne, 1987;Burrows et al, 1999;Bogumil et al, 2003) is used for ozone profile retrievals at highest possible altitudes (see Rohen et al (2005); Rohen (2006); Rohen et al (2006) for a description of the algorithm).…”

Abstract. SCIAMACHY limb scatter radiance measurements at selected wavelengths in the HARTLEY bands have been used to retrieve ozone profiles in the upper stratosphere and lower mesosphere. Comparisons with profiles measured by a ground based radiometer in Norway, MIPAS on board ENVISAT, HALOE on UARS and MLS on AURA indicate an agreement within 15% between 40 and 55 km and show that the retrieval provides reliable ozone profiles at these altitudes. Above 55 km, an increasing overestimation is observed. Beside the profile comparisons, further retrieval features of the current retrieval (version 1.26) are described.
