Abstract:

Total Ozone Mapping Spectrometer (TOMS)instruments have been successfully flown in orbit aboard the Nimbus-7(Nov. 1978 - May 1993), Meteor-3 (Aug. 1991 - Dec. 1994), Earth Probe (July 1996 - current), and ADEOS (Sep. 1996 - June 1997) satellites. Since last thirty years, TOMS data have been providing useful information related to the ozone depletion, recovery and global trend. The Earth Probe, Meteor-3 and Nimbus-7 Total Ozone Mapping Spectrometer (TOMS) data are currently reprocessed using version-8 algorithm ( http://toms.gsfc.nasa.gov/version8/v8toms_atbd.pdf ). The TOMS version 8 daily Level-2 swath data product consists of total column ozone, aerosol index, and Lambertian effective surface reflectivity (Rayleigh corrected) at approximately 50x50 km resolution (at nadir). This product also contains some auxiliary derived and ancillary parameters including N-values, SO2 index, cloud fraction, cloud pressure, ozone below clouds, terrain height, geolocation, solar and satellite viewing angles, and data quality flags. These Level-2 data are stored in the EOS version of Hierarchical Data Format 5 (HDF-EOS5) and are available ( http://mirador.gsfc.nasa.gov/) from the Goddard Earth Sciences (GES) Distributed Active Archive Center (DAAC). TOMS Levle-3 (Global Gridded 1x1.25 deg) are also available from the GES DISC. The GES DISC DAAC maintains an online Web-based browser for previewing the data, subsetting in ASCII format and downloading the data and images. The URL for the TOMS browser is http://giovanni.gsfc.nasa.gov/toms/ For more information regarding TOMS or other DAAC data sets please visit the DAAC Home Page at http://disc.sci.gsfc.nasa.gov/acdisc/ , or contact the DAAC Help Desk at: GSFC DAAC Help Desk NASA Goddard Space Flight Center Code 610.2 Greenbelt, MD 20771 gsfc-help-disc@lists.nasa.gov TOMS data are produced by the Laboratory for Atmospheres at NASA Goddard Space Flight Center (Code 613.1). The Version-8 Algorithm Theoretial Basis Document (ATBD)is available from the TOMS site http://toms.gsfc.nasa.gov/version8/v8toms_atbd.pdf The Level-3 data from Nimbus-7 TOMS, Meteor-3 TOMS, and Earth Probe TOMS are also made available from the Code 916 TOMS site in the ASCII format. For detailed information about the TOMS instrument, data, and ozone see the TOMS official Home Page at: http://toms.gsfc.nasa.gov/
