Recently the performance verification phase of the Ozone Monitoring Instrument (OMI) was successfully completed and the calibration has started. The OMI is a next generation imaging spectrograph suitable for trace gas retrieval using the UV-Visible wavelength range. The instrument combines a wide field-of-view (114 degrees) with high spatial resolution enabling trace gas retrieval in the troposphere and providing continuous monitoring. The paper summarises the important performance aspects for the OMI such as the spectral, radiometric, polarisation, viewing and stray light properties of the instrument. It focuses on some aspects that we consider of particular importance such as polarisation scrambling and diffuser features. These features can potentially mix with trace gas absorption features and thereby form error sources. Historically an important issue is the spectral stray light at the steep gradient in the Earth shine radiance around 300 nm. In this paper we show that OMI has a very good stray light performance at these wavelengths. The OMI will be launched on NASA's EOS-AURA satellite early 2004.
