AB: Little more than one year after First Light, data products of minor trace species from the Ozone Monitoring Instrument are beginning to mature, showing great potential for atmospheric chemistry studies: BrO, an important element in stratospheric ozone depletion due to its high efficiency in destroying ozone molecules, has matured to a level that is comparable to what was previously achieved from measurements of the Global Ozone Monitoring Experiment. Recent progress in the retrieval of HCHO, a volatile organic compound (VOC) produced from methane oxidation and isoprene emissions, and an indicator for urban air quality, has significantly enhanced the quality of this data product and has brought into reach its utilization in air quality studies. We will give an overview of the retrieval algorithm and an update on the current state of BrO and HCHO operational data products from OMI. Updates on the (currently inconclusive) retrieval of OClO, like BrO an element in the destruction of stratospheric ozone, will be included if sufficient progress is made by the time of the meeting. Finally, first results on the retrieval of CHOCHO (glyoxal) will be presented. The observation of CHOCHO, a VOC recently detected in ground-based measurements over Mexico City, constitutes the first-ever measurement of this elusive indicator of air quality from a satellite instrument.
