Abstract:
The second Release of Collection 003 of OMI/Aura Global Gridded Nitrogen Dioxide Product 'OMNO2G' is now available, from the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC). http://disc.sci.gsfc.nasa.gov/Aura/data-holdings/OMI/omno2g_v003.shtml 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 (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's (Dr. Pieternel Levelt) institute is the KNMI (Royal Netherlands Meteorological Institute). 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 OMNO2 and OMNO2G are NASA OMI scientist Dr. Nickolay Krotkov and KNMI Scientist Dr. Pepijn Veefkind. OMNO2G data product is a special Level-2 Gridded Product where pixel level data are binned into 0.25x0.25 degree global grids. It contains the data for all L2 scenes that have observation time betweeen UTC times of 00:00:00 and 23:59:59.9999. All data pixels that fall in a grid box are saved Without Averaging. Scientist can apply data filtering scheme of their choice and create new gridded products. The GES DISC developed interactive tool Giovanni ( http://giovanni.gsfc.nasa.gov/ ) provides on-line web based capabilities to browse and explore these data. The OMNO2G data product contains almost all parameters that are contained in OMNO2 product. OMNO2G data are stored in EOS Hierarchical Data Format (HDF-EOS5). Each file contains data from the day lit portion of the orbit (~14 orbits). The average file size for the OMNO2G data product is about 115 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 short Readme Document giving brief algorithm description and a document containing known data quality related issues for the OMNO2 product, the source of OMNO2G data have been provided by the OMNO2 Algorithm leads.( http://disc.gsfc.nasa.gov/Aura/OMI/omno2g_v003.shtml ) For more information on Ozone Monitoring Instrument and atmospheric data products, please visit the OMI-Aura sites: http://aura.gsfc.nasa.gov/ http://www.knmi.nl/omi/research/documents/ . Data Category Parameters: The OMNO2G data file consists of a Grid Data Object which contains complete information for each pixel binned into a grid. NO2 Parameters (and STD): Column Amount NO2, Column Amount NO2 Statosphere, Column Amount NO2 Troposphere, Slant Column Amount NO2, Atmospheric Mass Factors,--- Ancillary Data: Cloud Fraction (and STD), Cloud Pressure (and STD), Cloud Radiance Fraction Terrain Pressure, Terrain Reflectivity Quality Flags: VCD Quality Flags, Ground Pixel QualityFlags, Measurement QualityFlags Processing QualityFlags, Fit Quality Flags, Root Mean Square Error Of Fit Time and Geolocation Data: Time, Latitude, Longitude Solar Zenith Angle, Viewing Zenith Angle, Relative Azimuth Angle Line Number, Scene Number, Number Of Candidate Scenes For the full set of the Aura products available from the GES DISC, please see the link below. http://disc.sci.gsfc.nasa.gov/Aura/ Atmospheric Composition data from Aura and other satellite sensors can be ordered from the following site: http://disc.sci.gsfc.nasa.gov/acdisc/ |
