The reprocessed OMI/Aura Level-2 Zoomed Aerosol data product OMAEROZ at 13x12 km resolution has been made available from the NASA Goddard Earth Sciences Data and Information Services Center(http://disc.gsfc.nasa.gov/Aura/OMI/omaeroz_v003.shtml
) for the public access in March 2012.
There are two Level-2 Aura OMI aerosol products OMAERO and OMAERUV. The OMAERUV product uses the near-UV algorithm. ... The OMAERO (13x24 km resolution) and OMAEROZ (13x12 km resolution)is based on the multi-wavelength algorithm that uses up to 20 wavelength bands between 331 nm and 500 nm. The multi-wavelength retrieval algorithm is developed by the KNMI OMI Team Scientists. Drs. Deborah Stein-Zweers, Martin Sneep and Pepijn Veefkind are now the key investigators of this product. The OMAEROZ products contain Aerosol Optical Depths, Single Scattering Albedo, Aerosol Type, Aerosol Layer Height, and other intermediate and ancillary parameters and geolocation informations.
OMAEROZ files are stored in EOS Hierarchical Data Format (HDF-EOS5). Each file contains data from the day lit portion of an orbit (~53 minutes). OMAEROZ data files are based on Zoomed Level 1B radiance observations which are made once a month. Thus there is one day of zoomed data (approximately 14 orbits) per month. The maximum file size for the OMAEROZ data is about 11 Mbytes. A list of tools for browsing and extracting data from these files can be found at: http://disc.gsfc.nasa.gov/Aura/tools.shtml
A Readme document containing brief algorithm description and known data quality related issues and file spec are provided by the OMAERO Algorithm lead (see documents available from OMI product site http://disc.sci.gsfc.nasa.gov/Aura/data-holdings/OMI/omaeroz_v003.s...
The Ozone Monitoring Instrument (OMI) launched on NASA Aura satellite in July 2004, has been providing daily global measurements of clouds, atmospheric pollutants (Ozone, Nitrogen dioxide, Sulfur-dioxide, HCHO and Aerosols from biomass burning and industrial emissions), BrO and OClO for tracking ozone depletion and surface UV irradiance. 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's (Dr. Pieternel Levelt) institute is the KNMI (Royal Netherlands Meteorological Institute).
