Atmospheric measurements (satellite remote sensing): GOME measurements of stratospheric and tropospheric BrO

Measurements from the Global Ozone Monitoring Experiment (GOME) have been analysed for BrO absorption. An improvement to the existing data analysis method was required, to correct for a small angle dependency of the diffuser, leading to a significant improvement of the consistency of the BrO data set.

Evidence has been found for appreciable tropospheric contributions to the BrO atmospheric columns, both from the polar boundary layer in spring and a global BrO background. The latter has been further investigated resulting in an estimate of 0.5 - 2 ppt uniformly mixed BrO in the troposphere.

Results of this data analysis have been published and GOME data can also be accessed from the Institute web site. GOME data sets will be used within models of atmospheric chemistry. The expected benefit is to gain further understanding of atmospheric composition, now and in the future. In particular, modelling is being carried out, within THALOZ, in order to understand the BrO / Br / O3 relationship in the free troposphere.
