At [the recent ocean team workshop](https://forum.access-hive.org.au/t/ocean-team-workshop-12-15th-november-2024/3857/9) we’re curating a list of datasets that will be used by many people in the community and be available using ESMvaltool/re-gridded to om3 grids for easy comparison.

We’d like feedback on the best/most up to date datasets.

We now have ( **updated 21st Jan 2024 based on comments** – below):

- ERSST v4 (SST comparisons)
- SSH the most updated DUACS version is here: [Global Ocean Gridded L 4 Sea Surface Heights And Derived Variables Reprocessed 1993 Ongoing | Copernicus Marine Service](https://data.marine.copernicus.eu/product/SEALEVEL_GLO_PHY_L4_MY_008_047/description) . It covers the ice-covered Arctic and rest of open ocean (1993-2023). For the ice-covered southern Ocean there is this regional dataset [Antarctic - Sea Level Heights](https://www.aviso.altimetry.fr/en/data/products/sea-surface-height-products/regional/antarctic-sea-level-heights.html) which covers the whole southern ocean, including ice-covered and open ocean parts from 2013-2021. (a 2002-2021 version should be published this year.)
- WOA2023 (T and S comparisons). Already on Gadi (/g/data/ik11/observations/woa23)
- EN4: [Met Office Hadley Centre observations datasets](https://www.metoffice.gov.uk/hadobs/en4/) IAP: [http://www.ocean.iap.ac.cn/pages/dataService/dataService.html](http://www.ocean.iap.ac.cn/pages/dataService/dataService.html) These datasets have monthly historical T and S from the 1950s onwards, using different mapping methods and input profiles/corrections, so it is good to have the diversity of gridded products for analysis
- NSIDC CDR v5 (sea ice concentration). [NOAA/NSIDC Climate Data Record of Passive Microwave Sea Ice Concentration, Version 5 | National Snow and Ice Data Center](https://nsidc.org/data/g02202/versions/5)
- NSIDC sea ice index v3 (area and extent). [Sea Ice Index, Version 3 | National Snow and Ice Data Center](https://nsidc.org/data/g02135/versions/3)
- Tropical Atmosphere Ocean data. Want: subsurface temperature, fixed depth currents, subsurface salinity. [data](https://tao.ndbc.noaa.gov/tao/data_download/search_map.shtml). Related: [Forum post](https://forum.access-hive.org.au/t/access-om3-evaluation/1462/8)
- Chlorophyll. Sauzede et al., 2016 JGR Oceans

Perhaps @RyanHolmes, @Pearse, @Matthis_Auger, others might have some suggestions?

@taimoorsohail and @schmidt-christina in Hobart recently, we talked about T/S alternatives?
