The Total Ozone Mapping Spectrometer (TOMS) version 8 Daily Gridded Data consist of daily, global coverage of total column ozone, aerosol index, Lambertian effective reflectivity(Rayleigh corrected) and surface UV-B Erythemal irradiances.
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 temporal coverage of the Nimbus-7 TOMS data is from Nov 1978 to May 1993. 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 ozone, aerosol index, reflectivity data and UV-B Erythemal irradiances 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.
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/
The Level-2 data at instrument resolution(approx 50km x 50km pixel at nadir, in HDF5 EOS format) are also available from the GES DISC.

TOMS data are produced by the Laboratory for Atmospheres at NASA Goddard Space Flight Center (Code 916). The Version-8 Algorithm Theoretical Basis Document (ATBD) is available from the TOMS site http://ozoneaq.gsfc.nasa.gov/epsat.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. For detailed information about the TOMS instrument, data, and ozone see the TOMS official Home Page at: http://ozoneaq.gsfc.nasa.gov/
