This data product contains TOMS/Nimbus-7 UV-B Erythemal Local Noon Irradiance Monthly L3 Global 1x1.25 deg Lat/Lon Grid Version 8 data in ASCII format.
The Total Ozone Mapping Spectrometer (TOMS) Version 8 Monthly Gridded Data consist of monthly, global coverage of total column ozone, aerosol index, Lambertian effective reflectivity(Rayleigh corrected) and surface UV-B Erythemal irradiances. ... (The shortname for this Level-3 Nimbus-7 TOMS Product is TOMSN7L3mery)
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.
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.
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://ozoneaq.gsfc.nasa.gov/doc/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://ozoneaq.gsfc.nasa.gov/
