AB: We report progress in determining abundances of the trace gases BrO, OClO, and HCHO from the EOS-Aura Ozone Monitoring Instrument. Updates and improvements in the data analysis algorithm are described and examples of measurements given. OMI BrO includes releases from the shelf ice in 2004 Antarctic spring. HCHO includes production from biogenic sources, biomass burning, and possibly from agriculture and urban pollution. We will examine Asian HCHO production changes before and after the December 26, 2004 tsunami. OClO from Arctic spring 2005 will be presented if measurable enhancements have occurred in time to analyze and present at the meeting.
