The CCI programme is contributing to a rapidly expanding body of scientific knowledge demonstrating new insights in climate research by maximising the scientific benefits that satellite observations can provide. This was shown through the important contributions CCI made to the IPCC's 5th Assessment Report (WG1, 2013).
IPCC. In all, 27 CCI scientists were involved as leaders, contributing-authors or editors in seven of the 14 chapters of the IPCC AR5 WG1 report, and CCI results were cited 59 times.
Publication. The CCI scientific community have published 285 scientific articles in peer-reviewed journals, as of Dec 2015.
Quality. All CCI ECV data products have been fully error characterised, are provided with quantitative uncertainty estimates, and have been evaluated by leading members of the climate research community.
Operationalisation. Prototype processing systems for each ECV have been developed and validated in phase 1, and are being furthered developed during phase 2 to become operationally sustainable. This is a major step in making them suitable for transfer into the Copernicus Climate Change Service (C3S).
Open & Free. ECV products are being made available under an open and free data policy for uptake by the wider climate science community through the CCI Open Data Portal and via community initiatives such as ESGF and CMIP/obs4MIPs.
Community. Substantial community building has taken place to strengthen the relationship between satellite data product developers and climate scientists, and as a result of the multidisciplinary approach of the programme, strong links have also been forged spanning the land, ocean, atmosphere and cryosphere science communities.
