AB: In 2002 the on-ground calibration of the flight-model of the Ozone Monitoring Instrument (OMI), scheduled for launch in January 2004 on the EOS-AURA satellite, was performed by the industrial contractor in close cooperation with the Principal Investigator team from the Royal Netherlands Meteorological Institute (KNMI) and the scientific Calibration Working Group with members from The Netherlands, Finland, and the United States. OMI will observe the Earth in nadir with a field of view of 114 degrees, providing a daily Earth coverage. This presentation will focus on the measurements, analyses and preliminary results of the on-ground calibration from a scientific perspective, which are particularly important for meeting the scientific objectives of the OMI instrument. The OMI instrument is operated in flight at close to vacuum pressure and at temperatures of the CCD detectors and the instrument optical bench of 266 K and 265 K, respectively. Special attention is therefor given to the methods for obtaining a flight-representative on-ground calibration of the instrument. The OMI instrument has a large observational swath field of view of 114 degrees and a high spectral resolution. For this reason the on-ground calibration of the swath angle dependence of the radiometric calibration and the calibration description of spectral instrument features are discussed in the presentation.
