SBUV (Version 8.6) MERGED TOTAL AND PROFILE OZONE DATA SETS
The SBUV MERGED OZONE DATA SETS are monthly-mean zonal and gridded average products constructed by merging individual SBUV/SBUV/2 (total and profile ozone) satellite data sets. NO external calibration adjustment have been applied. Intercalibration of the SBUV instruments in Version 8.6 is accomplished within the algorithm at the radiance level. Remaining offsets (sub 10%, mostly sub 5% levels) between instruments exist, but their cause is not understood. We therefore do not make adjustments to the data. Rather we set limitations on the data included in the merged product based on data quality analysis by the instrument team and on comparisons with independent measurements. Details of the instruments/algorithm, data selection and construction of the final data sets are provided by following the links above.

|5° ZONAL MEAN||Daily Merged Overpass|
**Note that the 5° Zonal Mean file is in a new format that includes both profile and total
ozone data. The total ozone data in the previous format is available here.
**The overpass files used to construct the Daily Merged Overpass Product are available here.
MOD 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: 04 September 2013
- Extend N16/N19 through July, 2013.
- Update full N16 record using most recent revised calibration.
- Update Daily Overpass Product using MOD Release 3 data selection.
Last Modification: 10 May 2013
- Update full N17/N18 records using most recent revised calibrations.
- Extend N16/N18 through 2012.
- Inlcude N19 record from launch in 2009 through 2012.
Last Modification: 25 Aug 2012
- Use only measurements made when instrument orbit is within 8am - 4pm Equator Crossing Time (ECT) range.
- Do not include N9 Data.
- Extend N11 to ECT of 5:50 pm to maintain coverage through 1994 - 1995.
- Profile Only: Filter data after eruptions of El Chichon and Mt. Pinatubo volcanos.
- Total Only: Include N9 Total Ozone solely to fill gaps in N11 coverage. Profile Ozone in these cases set to 0 (missing value).
- Construct Daily Overpass Product using MOD Release 1 data selection rules.
