Summary
Abstract:
The OMI/Aura Level-2G Total Column Ozone Data Product OMDOAO3G (Version 003) is now available ( http://disc.gsfc.nasa.gov/Aura/OMI/omdoao3g_v003.shtml ) from the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) for the public access. NASA's 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 Meteorological Institute (FMI), to the US EOS-Aura Mission. The principal investigator's (Dr. Pieternel Levelt) institute is the KNMI (Royal Netherlands Meteorological Institute).
OMI provides two Level-2 total column ozone products (OMTO3 and OMDOAO3) based on two different algorithms. This Level-2G global total column ozone product is derived from OMDOAO3 which is based on the Differential Absorption Spectroscopy (DOAS) fitting technique that essentially uses the OMI visible radiance values between 331.1 and 336.1 nm. In addition to the total ozone column this product also contains some auxiliary derived and ancillary input parameters e.g. ozone slant column density, ozone ghost column density etc. The short name for this Level-2 OMI ozone product is OMDOAO3G and the lead Algorithm scientist for this product and for OMDOAO3 (the data source of OMDOAO3G) is Dr. Pepijn Veefkind from KNMI.
OMDOAO3G product files are stored in Hierarchical Data Format (HDF-EOS5). Each daily file contains data from the day lit portion of the orbits (approx 14 orbits) and is roughly 80 MB in size. 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 Readme document containing brief algorithm description and known data quality related issues and file spec are provided by the OMDOAO3 Algorithm lead (see http://disc.gsfc.nasa.gov/Aura/OMI/omdoao3g_v003.shtml ).
