In the standard global measurement mode, OMI observes 60 ground pixels (13 km x 24 km at nadir) across the swath for each of the 557 channels of UV2 (307-383 nm) and 30 ground pixels (13 km x 48 km at nadir) for the 159 channels of UV1 (264-311 nm). Each file contains data from the day lit portion of an orbit (~53 minutes) and is roughly 180 MB in size. There are approximately 14 orbits per day. Once a month, in one orbit, OMI performs dark measurements, it does not perform radiance measurements. In addition, OMI performs spatial zoom measurements one day per month. For that day, this product also contains UV2 measurements that are rebinned from the spatial zoom-in measurements. In original spatial zoom mode the nadir ground pixel size is 13 x 12 km and measurements are available only for the UV2 and VIS wavelengths (306 to 432 nm). The shortname for this OMI Level-1B Product is OML1BRUG. The lead algorithm scientist for this product is Dr. Marcel Dobber from the Royal Netherlands Meteorological Institude (KNMI).
The OML1BRUG files are stored in the HDF4 based EOS Hierarchical Data Format (HDF-EOS). The radiances for the earth measurements (also referred as signal) and its precision are stored as a 16 bit mantissa and an 8-bit exponent. The signal can be computed using the equation: signal = mantissa x 10^exponent. For the precision, the same exponent is used as for the signal.

OMI data users must be aware of the following:
From April 5th 2016 onwards, the information derived from the Nominal Ice and Snow Extent (NISE) maps that is stored in the OMI Level-1B Ground Pixel Quality Flags is not been updating. The information in these flags is therefore now based on the latest available NISE map from April 4 2016. This is due to problems with the 37V channel of the DMSP F17 satellite from which the NISE maps are derived. This 37V channel generates erroneous data. No alternative source for these NISE maps is currently available. Note that this also impacts the quality of the Level-2 products.
The version 003 Level-1B product is the first public release. The quality of this product is not fully validated yet. Before using it in any publication please contact algorithm team leads for the current known problems and updates.OMIgov.nasa.esdis.umm.instrumentshortnameOzone Monitoring InstrumentNot providedAuragov.nasa.esdis.umm.projectshortnameEarth Observing System (EOS), AuraAuragov.nasa.esdis.umm.platformshortnameEarth Observing System, AuraEarth Observation Satellites
