OMI/Aura NO2 Cloud-Screened Total and Tropospheric Column Daily L3 Global 0.25deg Lat/Lon GridEntry ID: GES_DISC_OMNO2d_V003
Abstract: The OMI/Aura Level-3 Global Gridded (0.25x0.25 deg) Nitrogen Dioxide Product "OMNO2d" is now released (Jan 10, 2013) to the public from the NASA Goddard Earth Sciences Data and Information Services Center(GES DISC). The OMNO2 (Level-2) and OMNO2G (Level-2G, binned) processed earlier (in 2012) are also available from GES DISC. see http://disc.sci.gsfc.nasa.gov/Aura/data-holdings/OMI/
Nitrogen ... dioxide is an important chemical species in both, the stratosphere where it plays a key role in ozone chemistry, and in the troposphere where it is a precursor to ozone production. In the troposphere, it is produced in various combustion processes and in lightning and is an indicator of poor air quality.
The algorithm leads for the NO2 products are NASA OMI scientist Dr. Nickolay Krotkov and KNMI scientist Dr. Pepijn Veefkind.
OMNO2d data product is a Level-3 Gridded Product where pixel level data of good quality are binned and "averaged" into 0.25x0.25 degree global grids. This product contains Total column NO2 and Total Tropospheric Column NO2, for all atmospheric conditions, and for sky conditions where cloud fraction is less than 30 percent. Details are available in the documents provided on the NASA GES DISC OMI site http://disc.gsfc.nasa.gov/Aura/OMI/documents/v003/omno2d_v003.shtml
OMNO2d data are stored in EOS Hierarchical Data Format (HDF-EOS). Each file contains data from the day lit portion of the orbit (~14 orbits). The average file size for the OMNO2d data product is about 6 Mbytes.
A list of tools for browsing and extracting subset of data data from these files can be found at: http://disc.gsfc.nasa.gov/Aura/tools.shtml
The GES DISC has also developed an on-line web-based interactive tool called Giovanni (http://giovanni.gsfc.nasa.gov/) which provides web based capabilities to browse and explore OMI NO2 data.
The OMI along with other atmospheric chemistry sensors, flown on NASA Aura satellite 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 criteria pollutants (Tropospheric 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 Agency for Aerospace Programs (NIVR)in collaboration with Finish Meterological Institute (FMI), to the US EOS-Aura Mission. The principal investigator (Dr. Pieternel Levelt) institute is the KNMI (Royal Netherlands Meteorological Institute).
