Summary

Description

This data product contains TOMS/Meteor-3 UV Reflectivity Daily L3 Global 1x1.25 deg Lat/Lon Grid Version 8 data in ASCII format. (The shortname for this Meteor-3 TOMS Product is TOMSM3L3dref) 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 on the following satellites: Nimbus-7 (Nov. 1978 - May 1993), Meteor-3 (Aug. 1991 - Dec. 1994), Earth Probe (July 1996 - current), and ADEOS (Sep. 1996 - June 1997). Earth Probe, Meteor-3 and Nimbus-7 data are currently reprocessed using the Version-8 algorithm (http://toms.gsfc.nasa.gov/version8/v8toms_atbd.pdf) . These Version-8 data are archived at the Goddard Distributed Active Archive Center (DAAC). The total ozone, aerosol index, reflectivity data and UV-B Erythemal irradiances are mapped to a global grid of size 180 x 288 with a Lat/Lon resolution of 1.00 x 1.25 degrees. These data are also 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). The Version-8 Algorithm Theoretical Basis Document (ATBD) is available from the TOMS site http://toms.gsfc.nasa.gov/version8/v8toms_atbd.pdf For detailed information about the TOMS instrument, data, and ozone see the TOMS official Home Page at: http://toms.gsfc.nasa.gov/
