Summary

Abstract: The reprocessed OMI/Aura Level-2 zoomed cloud data product OMCLDO2Z at 13x12 km resolution is now available ( http://disc.gsfc.nasa.gov/Aura/OMI/omcldo2z_v003.shtml ) from the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) for the public access. It is the second release of Version 003 and was reprocessed late 2011.
OMI provides two cloud products based on two different ... algorithms, the Rotational Raman Scattering method and O2-O2 absorption method using the DOAS technique. This level-2 zoomed cloud product at the pixel resolution (13x12 km2 at nadir) is based on the spectral fitting of O2-O2 absorption band at 477 nm using DOAS technique. This product contains effective cloud pressure, effective cloud fraction, slant column O2-O2; uncertainties in derived, parameters, terrain and geolocation information, solar and satellite viewing angles, and quality flags.
The shortname for this Level-2 OMI cloud product is OMCLDO2Z and the lead scientist for this product is Dr. Pepijn Veefkind.
OMCLDO2Z files are stored in Hierarchical Data Format (HDF-EOS5). Each file contains data from the day lit portion of an orbit (~53 minutes) and is roughly 20 MB in size. OMCLDO2Z data files are based on Zoomed Level 1B radiance observations which are made once a month. Thus there is one zoomed cloud product per month.
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 OMCLDO2 Algorithm lead (see documents available from OMI product site
http://disc.sci.gsfc.nasa.gov/Aura/data-holdings/OMI/omcldo2z_v003....
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).
