Summary

Abstract: The OMI/Aura Level-2 Ozone Profile data product OMO3PR (Version 003) is now available ( http://disc.gsfc.nasa.gov/Aura/OMI/omo3pr_v003.shtml ) from the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) for the public access.

NASA Aura satellite sensors are tracking important atmospheric pollutants from space since its launch in July, 2004. The Ozone ... Monitoring Instrument (OMI), one of the four Aura satellite sensors with its 2600 km viewing swath width provides daily global measurements of four important US Environmental Protection Agency's criteria pollutants (Ozone, Nitrogen dioxide, Sulfur dioxide and Aerosols from biomass burning and industrial emissions), HCHO, BrO, OClO and surface UV irradiance. OMI is a contribution of the Netherlands Space Office (NSO) in collaboration with Finish Meterological Institute (FMI), to the US EOS-Aura Mission. The principal investigator's (Dr. Pieternel Levelt) institute is the KNMI (Royal Netherlands Meteorological Institute).

OMI Level-2 ozone profile product, OMO3PR at the pixel resolution 13x 48 km (at nadir), is based on the optimal estimation algorithm (Rodgers, 2000) with climatological ozone profiles as a-priori information. The OMO3PR retrieval algorithm uses spectral radiance values from the UV1 channel (270 nm to 308.5 nm) and from the first part of the UV2 channel (311.5 nm to 33 0 nm). OMO3PR product provides ozone values (in Dobson unit) for 18 atmospheric layers. It also provides a-priori ozone profile values, error covariance matrix, averaging kernel and some ancillary information such as time, latitude, longitude, solar zenith and viewing zenith angles and quality flags .

The short name for this Level-2 OMI ozone profile product is OMO3PR and the lead scientist for this product is Dr. Johan de Haan (johan.de.haan@knmi.nl).

OMO3PR product files are stored in Hierarchical Data Format (HDF-EOS5 ). Each file contains data from the day lit portion of an orbit (approx 53 minutes). There are approximately 14 orbits per day thus the total data volume is approximately 150 GB/day. 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 OMO3PR algorithm lead (see http://disc.gsfc.nasa.gov/Aura/OMI/omo3pr_v003.shtml ).

Quality The 'version 003' product is the second public release. It is based on
improved radiance calibration.

Use Constraints This Data set (version 003/second public release) is better than the
earlier version but it is not fully validated yet. Before using it in
any publication please contact algorithm team lead for the current
known problems and updates.
