The document is the OMI User's Guide, which provides an overview of the OMI instrument and OMI data products. The instrument is used for ozone monitoring, and the data products include radiometrically calibrated and geolocated radiance products, orbital atmospheric products, global binned atmospheric products, and global gridded atmospheric products.
The Ozone Monitoring Instrument (OMI) is a nadir‑viewing near‑UV/Visible CCD spectrometer on NASA’s Aura satellite. This guide provides background on the instrument, its mission objectives, and the scientific context for its measurements.
The manual describes the various OMI data products (Level 1B radiance, Level 2 atmospheric, Level 2G binned, Level 3 gridded), quality‑assessment procedures, and instructions for accessing and using the data through the DAACs and processing tools.
