EUMETSAT generates Climate Data Records for NWP model-based reanalysis, climate system analysis and climate modelling applications.
Climate activities of the Secretariat
The activities involve the generation of high-quality Fundamental Climate Data Records (FCDR), by recalibration and inter-satellite calibration of historic and current EUMETSAT sensor raw data records. For example, the Meteosat time series already covers more than 30 years and nine different satellites.
Differences between instruments need careful consideration to mitigate unwanted, spurious anomalies in the time series, caused by instrument and spacecraft behaviour in space.
The secretariat also produces a limited number of Thematic Climate Data Records (TCDR). Climate products
The secretariat activities are governed by the Climate Service Development Plan, that also provides a comprehensive list of the planned releases of climate data records until 2018. Many of the climate data records are produced as part of European and international collaboration projects, including ERA-CLIM2, QA4ECV and SCOPE-CM.

Cooperative climate projects
The project, led by ECMWF, aims to produce global coupled reanalyses that involve consistent descriptions of the global atmosphere, ocean, land-surface, cryosphere and carbon cycle. A particular reanalysis for the last 50 years makes massive use of satellite data provided by EUMETSAT, starting in the 1970s. This reanalysis is planned to be continued in close-to-real time to enable an important part of the Copernicus Climate Change Service.
Satellite data users need to be able to make rapid judgments on the validity and trustworthiness of Earth Observation data and the derived climate data sets. The QA4ECV (Quality Assurance for Essential Climate Variable) project, led by KNMI, develops a Quality Assurance (QA) system for observational data products. EUMETSAT establishes a traceable uncertainty characterisation for the surface albedo derived from Meteosat satellites, which forms an input for a global surface albedo product from a combination of several instruments in geostationary and polar orbit.

One of the main outcomes of the ALBEDOVAL2 study was the collection of a set of validation points, correlated with various ancillary data, to fully characterise the sites for land product validation and in particular for Albedo.
This information is available on our Surface Albedo Validation Sites (SAVS) website.
The CORE-CLIMAX project performed coordination around the establishment of the Copernicus Climate Change Service, in the context of global reanalysis such as provided by ERA-CLIM2. EUMETSAT with its partners performed a European-wide assessment of the maturity of Climate Data Records (CDR) production capacity. 35 climate data records have been assessed, including those from the SAF network and the ESA Climate Change Initiative (CCI).

SCOPE-CM (Sustained and COordinated Processing of Environmental satellite data for Climate Monitoring) is a network of agencies and operators of environmental satellite systems, and interfaces with WMO, WCRP, GCOS, CGMS, CEOS and GEO. It offers its support to coordinate and facilitate international activities to generate CDR from multi-agency satellite data.
Within SCOPE-CM, the contributing organisations coordinate their scientific and technical development activities, and cooperate on the basis of shared and distributed responsibilities for the generation of global products.
The SCOPE-CM network was established in November 2008. The participating organisations include the operators of operational satellites: EUMETSAT, China Meteorological Administration, Japanese Meteorological Agency, and NOAA.
