Ozone Monitoring Instrument (OMI)


Information updated on Thu Apr 10 19:10:30 2008


General Data Description

The OMI instrument distinguishes between aerosol types, such as smoke, dust, and sulfates, and can measure cloud pressure and coverage, which provide data to derive tropospheric ozone. OMI continues the TOMS record for total ozone and other atmospheric parameters related to ozone chemistry and climate. The OMI instrument is mounted on the EOS Aura platform. The OMI instrument employs hyperspectral imaging in a push-broom mode to observe solar backscatter radiation in the visible and ultraviolet. The hyperspectral capabilities improve the accuracy and precision of the total ozone amounts and also allow for accurate radiometric and wavelength self calibration over the long term. The instrument 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.

Reprocessing History

Reprocessing Date

The OMI (Ozone Monitoring Instrument) datastream "gecomiX1.a1" has recently been changed and reprocessed from October, 2004 to present. The reprocessed data, known as "Collection 3" data, have been reprocessed with revised calibration. Also, the grid has changed from a 1x1.25 degree latitude/longitude grid to a 1x1 degree grid and the reflectivity data have been replaced with radiative cloud fraction.

XDC reprocessed all the omi data back to 200410 and sent them to the Archive on April 10, 2008.
