Update: August 23, 2004 -Version 8 data and products of the TOMS processing algorithm are now available on line through the TOMS web site and via anonymous ftp. Data and products for the Nimbus-7, Meteor-3 (as of August 9, 2006), and Earth Probe instruments use the new Version 8 of the TOMS processing algorithm. Data and products for the Adeos instrument are still the result of Version 7 processing with no immediate plans to re-process the Adeos data. Update: May 26, 2004 - Version 8 data are now available for the
entire Nimbus-7 data record (November 1978 through May 1993) and for the
Earth Probe data record from August 1996 through August 2003 via
anonymous ftp
as .zip files. Each .zip file contains the compressed
individual files. Update: May 21, 2004 - Data from Nimbus-7 TOMS (11/1978 through
05/1993) and Earth Probe TOMS (08/1996 through 08/2003) have been
reprocessed and will be distributed at the 2004 Quadrennial Ozone
Symposium in June 2004. A 2 DVD set contains data and images from both
instruments for all of the TOMS products: ozone, aerosol, reflectivity,
and erythemal UV. Copies of the DVD's can be obtained from the
Goddard Space Flight Center's Distributed Active Archive Center (DAAC) We have developed a new Version of the TOMS retrieval algorithm.
A preliminary Algorithm Theoretical Basis
Document (ATBD) is now available. The new algorithm uses a set of
fixed standard ozone profiles similar to the previous algorithm and then
updates the solution based on a new
climatology of ozone and temperature profiles that are dependent
on month, latitude, and total ozone. Here is a list of the
Version 8 enhancements:
