1970-2021 Profile and Total Column Ozone from the SBUV Instrument Series


The SBUV MERGED OZONE DATA SETS are monthly-mean zonal and gridded average products constructed by merging individual SBUV and SBUV/2 (total and profile ozone) satellite data sets. NO external calibration adjustments have been applied. Intercalibration of the SBUV instruments in Version 8.7 is accomplished within the algorithm at the radiance level. Version 8.7 uses the same core algorithm as Version 8.6, but includes new inter-instrument calibration adjustments for instrument records since 2000 (NOAA-16 SBUV/2 though OMPS NP) based on a new approach to radiance intercomparisons across overlapping instruments. Version 8.7 also incorporates an updated a priori with improved tropopsheric represetation and diurnal adjustments to ensure the a priori profile correctly reflects the local solar time of each measurement. A post-retrieval diurnal correction is applied to adjust each instrument record to an equivalent measurement time of 1:30pm. Remaining offsets (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.

MOD v2 Release 1
Jan 1970 - Dec 2021
Last Modified 21 May 2022

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: 21 May 2022

v2 Release 1 Extended:

  • MOD v2 Release 1 Replace all instrument records with v8.7 retrievals (v2.8 for OMPS NP)
  • No longer include N14am SBUV/2 in MOD record based on updated radiance intercomparisons
  • No longer include N16am SBUV/2 in MOD record based on updated radiance intercomparisons
  • Extend OMPS NP V2.8 (equivalent to SBUV V8.7) through December 2021.
  • Extend Daily Overpass Product using MOD v2 Release 1 data selection.
