Copernicus Climate Change Service

Climate Change Services are essential to climate change adaptation, as they provide climate and climate change information and knowledge by means of accessible, reliable, timely, and user oriented products.

Copernicus is the European Union’s Earth Observation Programme. It consists of a complex set of systems which collect data from multiple sources: earth observation satellites and in situ sensors such as ground stations, airborne and sea borne sensors. Copernicus processes these data and provides users with information through a set of services that address six thematic areas: land, marine, atmosphere, climate change, emergency management and security.

Copernicus Climate Change Service (C3S) provides climate change services that support European climate policies and actions, contributing to building a European society with more resilience against human-induced changing climate.

Copernicus Climate Change Service gives access to information about the past, current and future states of the climate in Europe and worldwide. The portfolio of products will include:

  • Consistent estimates of multiple Essential Climate Variables (ECV)
  • Global and regional reanalysis
  • Products based on observations alone (analysis)
  • A near real time climate monitoring facility
  • Seasonal forecast
  • Climate projections at global and regional scales
  • Tailored information for socio-economic sectors

The Copernicus Climate Change Service is under implementation. In November 2014, the European Commission signed a Delegation Agreement with ECMWF (European Centre for Medium-Range Weather Forecasts) for the implementation of the service. The operational capacity is planned for the third year of the service and it is preceded by a pre-operational stage.

The pre-operational stage includes the following five projects that address specific topics for the Copernicus Climate Change Service:

  • ERA-CLIM2: European Reanalysis of the Global Climate System
  • UERRA: Uncertainties in Ensembles of Regional Re-Analysis
  • QA4ECV: Quality Assurance for Essential Climate Variables
  • CLIPC: A Climate Information Portal for Copernicus
  • EUCLEIA: European climate and weather events: interpretation and attribution
