Summary

Description

The Metero-3 Total Ozone Mapping Spectrometer (TOMS) version 8 Daily Gridded Data consist of daily, global coverage of total column ozone and UV-B Lambertian effective surface reflectivity (Rayleigh corrected). Four TOMS instruments have been successfully flown in orbit aboard the Nimbus-7 (Nov. 1978 - May 1993), Meteor-3 (Aug. 1991 - Dec. 1994), ADEOS (Sep. 1996 - June 1997) and Earth Probe (July 1996 - 2005) satellites. (The shortname for this Meteor-3 TOMS Product is TOMSM3L3) The temporal coverage of the Meteor-3 TOMS data is from Aug 1991 to Dec 1994. Nimbus-7, Meteor-3, and Earth Probe TOMS data have been reprocessed using version-8 algorithm. These data are archived at the Goddard Distributed Active Archive Center (DAAC). The Total column ozone and Effective surface reflectivity data for the Meteor-3 TOMS are mapped to a global grid of size 180 x 288 with a lat-long resolution of 1.00 x 1.25 degrees. These data are stored in the EOS version of Hierarchical Data Format (HDF-EOS). HDF was developed by the National Center for Supercomputer Applications (NCSA) at the University of Illinois at Urbana-Champaign. TOMS data are produced by the Laboratory for Atmospheres at NASA Goddard Space Flight Center (Code 613.1). The Version-8 Algorithm Theoretical Basis Document (ATBD)is available from the TOMS site http://ozoneaq.gsfc.nasa.gov/m3sat.md 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.
