Production of peer-reviewed papers on ozone profile intercomparisons of data sets and long term (1979-now) combined datasets.
Results of ACC Meeting (June 4-5, 2014) (a) Results of recent total ozone intercomparison and validation activities were discussed. Intensive activities supported by both the ESA Ozone_cci and NASA/NOAA have enabled advances in error quantification and comparisons between multiple data sets and ground based data. Very good agreement between long term SBUV and the latest Ozone_cci total ozone data set have been found. (b) The integration of IR sensor data, e.g., IASI and AIRS, was discussed. Projects in the USA (SBUV/AIRS) and Europe (GOME/IASI) are being planned to produce such data sets. (c) Proposals to produce a combined monthly zonal mean total ozone set and a combined gridded product were discussed, recognizing the science needs for these products. It was agreed to produce combined monthly mean data sets with a grid of 5x5 degrees. (d) It was agreed to extend the ongoing total ozone intercomparison / combination activities to nadir profiling (to be discussed in detail at the next ACC meeting).(Update from June 2015 SIT Chair TagUp)?Meeting at ESRIN covered both total ozone and nadir profiles, which is a new, using SBUV, GOME, GOME 2, SCIAMACHY and soon IASI. Concerning total ozone, there is still work to be done on higher-level products. The action can be considered CLOSED for Level 1 and 2. Zonal mean is still on going and consideration is given to a Level 3 product with a spatial resolution of 5?x5? (the ESA ozone_cci product is available at 1?x1? resolution) using a new interpolation algorithm for SBUV.In discussion with SIT Chair 6/2016, decided to keep this deliverable open to bring continued visibility to the ongoing efforts.2017/03 Update: 1) Total ozone: anticipate project completion Q4 2017 with a peer-reviewed paper on intercomparisons of long term combined gridded data records. 2) Nadir ozone profiles and tropospheric ozone: initiate the comparison of zonal mean data records. Publication not anticipated until Q4 2018 at earliest.2017/10 Update: 1) Total ozone: Paper on intercomparisons of long term combined gridded data records has been submitted and is in peer review. The gridded ozone record is planned to be updated annually as observations continue to be made operationally. 2) Nadir ozone profiles and tropospheric ozone: activities are ongoing and will be discussed in future AC-VC meetings before recommending specific next steps on constellation activities and deliverables.2018/03 Update: The description has been modified slightly to clairfy current focus on Ozone profile datasets. It used to cover both total column and profile data, however the part on total column data has been addressed by publications.2018/08 Update: Status of ozone profile datasets was discussed during AC-VC-14 in May 2018. Progress is being made on individual datasets. The team is not yet ready to define a specific harmonized target deliverable, but wishes to keep this action open as scheduled in order to stimulate further progress.
2019/09/09 Status: With the submission of peer-reviewed papers on intercomparisons of satellite total column ozone, the total ozone part of VC-02 is now completed. Total ozone ECV products will continue to be produced operationally. AC-VC is now undertaking a new target deliverable for intercomparison of the various existing and new tropospheric column ozone products. AC-VC proposes to conduct a rigorous intercomparison exercise followed by submission of a peer-reviewed journal article by Q4 2022.
Formerly CEOS Action # IN-01-C2_2
2019/09/16 Following discussion during SIT-TW 2019, propose to add new deliverable on tropospheric column ozone with a target completion date of Q4 2022.
