Daily sea surface temperature (°C) averaged over the extrapolar global ocean (60°S-60°N) during 2023 (black line) and for 1979 to 2022 (grey lines). The average conditions for 1991-2020 are shown by the dashed grey line. The previous global average SST record, from March 2016, is shown by the labelled horizontal dashed grey line.

Space ConneXions Ireland (SCL-IRE) leads our work on Copernicus projects, including the technical support for the management of ECMWF's Essential Climate Variable (ECV) contracts, which are providing Earth observation data for the Copernicus Climate Change Service (C3S) Climate Data Store. The ECV datasets and documentation on the CDS allow users to exploit the satellite observations that help to keep society informed about the Earth’s past and present climate.

Our project supports the management of the ECV contracts that supply the data and documentation to the CDS and includes the organisation and review of the C3S ECV contractors’ deliverables. We work with ECMWF and lead a team of ECV experts from various European companies including Randbee, University College Cork (UCC), National University of Ireland, Galway (NUIG), NILU and b.geos, who work with the ECVs contractors to ensure the high quality of the documentation and data that is ingested into the Climate Data Store.
