AB: The Ozone Monitoring Instrument (OMI) is the Dutch-Finnish contribution to the NASA EOS-Aura platform, which was launched in July 2004. OMI is the first of a new generation of UV-Visible spaceborne spectrometers that use two dimensional detectors. These detectors enable OMI to measure atmospheric trace gases and aerosols over the entire Earth within a single day and with high spatial resolution (13x24 km² at nadir), which makes this instrument extremely suitable for tropospheric research. Several of the OMI products contain information on the troposphere: the ozone total column and ozone profile, columns of NO₂, SO₂, HCHO, and aerosol optical thickness and aerosol absorption. The strength of OMI is that the combining the information on these constituents leads to better insight in tropospheric composition. The information may be further enhanced by adding data from other sensors on the Aura platform, as well as from the A-train satellite constellation. In this contribution case studies on tropospheric events will be discussed that show the capabilities of the OMI data. One of these case studies focuses on a biomass burning event, and shows that a combination of different OMI products, for example NO₂ columns and aerosol properties, provides a unique view on such events. By applying this approach, information is obtained on the source strength, as well as the transport and removal of biomass burning plumes.
