AB: First measurements from the space-borne instrument SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY) have been analyzed for BrO absorption using the Differential Optical Absorption Spectroscopy (DOAS) method. As a result of polarization residual structures in channel 2 of the SCIAMACHY instrument, a UV-shifted spectral range was utilized in the BrO column retrieval from nadir SCIAMACHY lv-0 data in contrast to the `traditional' wavelength window employed for the GOME (Global Ozone Monitoring Experiment) BrO retrieval. In this study, direct comparisons of the BrO total column have been made to columns retrieved from the GOME instrument and values observed to agree qualitatively. The results are also discussed in view of indications for a tropospheric background of BrO.
