Abstract:
The Level-1B (L1B) Radiance Product OML1BRUG (Version-3) from the Aura-OMI is now available to public (http://disc.gsfc.nasa.gov/Aura/OMI/oml1brug_v003.shtml) from the NASA GSFC Earth Sciences Data and Information Services Center (GES DISC). The Ozone Monitoring Instrument (OMI), an ultraviolet-visible imaging spectrometer was launched aboard the EOS-Aura satellite on July 15, 2004(1:38 pm equator crossing time, ascending mode on the day side). OMI with its 2600 km viewing swath width (60 cross track and about 1650 along track pixels) provides almost daily global coverage. OMI is a contribution of the Netherlands Space Office (NSO) in collaboration with Finish Meteorological Institute (FMI), to the US EOS-Aura Mission. The principal investigator (Dr. Pieternel Levelt) institute is the KNMI (Royal Netherlands Meteorological Institute). OMI is designed to monitor stratospheric and tropospheric ozone, clouds, aerosols and smoke from biomass burning, SO2 from volcanic eruptions, and key tropospheric pollutants (HCHO and NO2) and ozone depleting gases (OClO and BrO). OMI calibrated and geolocated radiances for the channels in the UV1(264-311 nm), UV2 (307-383 nm) and VIS (349-504) regions, spectral irradiances, calibration measurements, and all derived geophysical atmospheric products are archived at the NASA Goddard DAAC. The shortname for this OMI Level-1B Product is OML1BRUG and the lead algorithm scientist for this product is Dr. Marcel Dobber from the KNMI. This Radiance product contains geolocated Earth view spectral radiances from the UV detectors in the wavelength range of 264 to 383 nm. 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). 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). OML1BRUG files are stored in EOS Hierarchical Data Format (HDF-EOS 2.4) which is based on HDF4. The radiance 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 = signal_mantissa x 10 exponent . For the precision, the same exponent is used as for the signal. Each file contains data from the day lit portion of an orbit (~53 minutes) and is roughly 484 MB in size. There are approximately 14 orbits per day. For browsing and extracting data from these files, some software and tools are made available from the site: http://disc.gsfc.nasa.gov/Aura/tools.shtml A list of all of the OMI data products and the documents related to algorithm, data quality and file format specifics are available from the site: http://disc.gsfc.nasa.gov/Aura/OMI/ For more information on Ozone Monitoring Instrument and atmospheric data products, please visit the OMI-Aura sites: http://aura.gsfc.nasa.gov/ http://www.knmi.nl/omi/research/documents/
