TOMS/SBUV MERGED TOTAL AND PROFILE OZONE DATA SETS


**MOD Update through April 2009 Now Available**


The MERGED OZONE DATA SETS are monthly-mean zonal and gridded average products constructed by merging individual TOMS/OMI (total ozone) and SBUV/SBUV/2 (total and profile ozone) satellite data sets. An external calibration adjustment has been applied to each satellite data set in an effort to calibrate all the instruments to a common standard. Details of the external calibrations and construction of the final data sets are provided by following the links at the top of the page.

* The NOAA-17 data from the beginning of the record have been reprocessed using the best calibration information available through July 2008.  Data processed after July 2008 use an extrapolated calibration that does not correct for solar activity variations, which can increase the uncertainty in daily profile data, but is less significant for broadly averaged total ozone data.  The MOD data set will be updated as new calibrations become available (~yearly) but changes to total ozone are expected to be small.

New Section Data Set Modifications

Periodic updates will be made as new data become available, adding to and possibly changing ozone values at the end of the data set. Changes to existing data may occur as updates to particular data sets become available, and are averaged with the data previously included in the merged data set. These changes are tracked below.

Last Modification: 1 May 2009

Revision 05 Total Ozone Data Set

Revision 01 Profile Ozone Data Set

Revision 00 Profile Ozone Data Set

Modification History (includes Previous Revisions of MOD Data using Version 8 Data
