Definition

  • The Ozone Monitoring Instrument (OMI) is a contribution of the Netherlands's Agency for Aerospace Programs (NIVR) in collaboration with the Finnish Meteorological Institute (FMI) to the EOS Aura mission. It will continue the TOMS record for total ozone and other atmospheric parameters related to ozone chemistry and climate. OMI measurements will be highly synergistic with the other instruments on the EOS Aura platform. The OMI instrument employs hyper spectral imaging in a push-broom mode to observe solar backscatter radiation in the visible and ultraviolet. The Earth will be viewed in 740 wavelength bands along the satellite track with a swath large enough to provide global coverage in 14 orbits (1 day). The nominal 13 x 24 km spatial resolution can be zoomed to 13 x 13 km for detecting and tracking urban-scale pollution sources. The hyper spectral capabilities will improve the accuracy and precision of the total ozone amounts. The hyper spectral capabilities will also allow for accurate radiometric and wavelength self calibration over the long term. The expanded wavelength characteristics will provide the following features. Continue global total ozone trends from satellite measurements beginning in 1970 with BUV on Nimbus-4. Map ozone profiles at 36 x 48 km, a spatial resolution never achieved before. Measure key air quality components such as NO2, SO2, BrO, OClO, and aerosol characteristics. Distinguish between aerosol types, such as smoke, dust, and sulfates. Measure cloud pressure and coverage, which provide data to derive tropospheric ozone. Map global distribution and trends in UV-B radiation. A combination of algorithms including TOMS version 7, Differential Optical Absorption Spectroscopy (DOAS), Hyper spectral BUV Retrievals and forward modeling will be used together to extract the various OMI data products. Near Real Time (NRT) production of ozone and other trace gases.
