Tropospheric Observations with the Ozone Monitoring Instrument (OMI)
(1) KNMI, PO Box 201, De Bilt, Netherlands
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 (13 km by 24 km 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.
In this contribution case studies on tropospheric events will be discussed that show the capabilities of the OMI data. Using more than one year of OMI data, analyses on air quality in Europe will be presented that make use of the unique spatial resolution and daily global coverage of this dataset.
