Abstract: The OMI Earth Surface Reflectance Climatology product, OMLER (Global 0.5deg Lat/Lon grid) which is based on Version 003 Level-1B top of atmosphere upwelling radiance and incoming irradiance, is now available ( http://disc.gsfc.nasa.gov/Aura/OMI/omler_v003.shtml ) from the NASA Goddard 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 from 159 channels in UV1(264-311 nm), 557 channels in UV2 (307-383 nm) and 751 channels in VIS (349-504) spectral regions, spectral irradiances, calibration measurements, and all derived geophysical atmospheric products (Level-2 and 3) are archived at the NASA Goddard DAAC.
The shortname for this OMI Level-3 Product is OMLER and the lead algorithm scientists for this product are KNMI scientists Dr. Quintus Kleipool and Dr. Marcel Dobber.
OMLER spectral surface reflectance product contains monthly and yearly climatology of the Earth's surface Lambert Equivalent Reflectance (LER) for 23 wavelengths in the spectral range 309 to 500 nm, at a spatial resolution of 0.5 by 0.5 degrees. This LER is defined as the required reflectance of an isotropic surface needed to match the observed top of the atmosphere (TOA) reflectance in a pure Rayleigh scattering atmosphere under cloud free conditions and no aerosols. The climatology is based on statistical analysis of the three years of OMI version 03 radiance data (Oct 2004-Oct 2007). This product also provides minimum spectral surface reflectivity observed for each 0.5 deg Lat/Lon grid during the three years period.
The OMLER product file is produced in Hierarchical Data Format (HDF-EOS5). It is roughly 300 MB in size. For browsing and extracting data from Aura data files, some software and tools have been made available from the Aura GES DISC tools site: http://disc.gsfc.nasa.gov/Aura/tools.shtml
A Readme document containing brief algorithm description and file spec provided by the OMLER Algorithm lead is available from the GES DISC data product site http://disc.gsfc.nasa.gov/Aura/OMI/omler_v003.shtml
