Improvements to the retrieval of tropospheric NO₂ from satellite – stratospheric correction using SCIAMACHY limb/nadir matching and comparison to Oslo CTM2 simulations

In general, over the cleanest areas (open-ocean and high-latitude regions), the SP2 algo- rithm yields V strat values that are approximately as accurate as the NO2 slant columns

In this section, stratospheric BrO profiles and correspond- ing partial columns retrieved from ground-based UV-visible measurements at Harestua, OHP, and Lauder are compared

Vertical and slant tropospheric NO 2 -columns from the new satellite instrument SCIA- MACHY on ENVISAT are validated by measurements of the Airborne Multi AXis DOAS

We have presented consolidated time series of stratospheric NO 2 vertical columns at the NDACC station of Jungfraujoch retrieved from ground-based FTIR and SAOZ observations as well

The stratospheric BrO vertical profiles obtained by the Mi- crowave Limb Sounder (MLS) on the Aura satellite (Ko- valenko et al., 2008) has not been used for our comparisons,

Since a good reduced chi squared and small residual RMS may not mean necessarily that the fit and/or the fitting func- tion are good, a visual examination of the residuals is

A proof-of-concept study for the retrieval of stratospheric aerosol extinction from limb scatter measurements was previously pub- lished and the Version 5 data product retrievals

We also present a relative limb correction scheme (RLC), where the limb data is “corrected” for the ref- erence sector (RS), analogue to the nadir RSM, and just the
