BrO profile by IFE/IUP Bremen (last update: 12 Jul 2010)
validation summary Comparisons of BrO vertical profiles retrieved at IUP Bremen from SCIAMACHY limb measurements (version 3.2) to the results obtained from ground-based measurements are presented by Hendrick et al. 2009. The latter results are obtained at IASB-BIRA applying the profiling algorithm to ground-based zenith sky measurements of the scattered solar light. The comparison reveal a good agreement between both techniques. In the altitude range between 15 and 27 km the retrieved BrO profiles are found to agree better than 20%. Due to data availability issues comparisons are only done for three selected locations, namely, over Harestua (60N), OHP (45N), and Lauder (45S) ground stations.
available data September 2002 - April 2012. Data is available via the SCIA-ARC website. Restrictions for data use do apply.
