ICARE: Cloud-Aerosol-Water-Radiation Interactions


The ICARE Data and Services Centre is the result of a specific partnership between the Hauts-de-France region, the CNES, the CNRS and the University of Lille and is one of the 4 data centres of the national data and services infrastructure for the atmosphere AERIS set up in 2014. Its mission is to provide the scientific community with services designed to facilitate the use of “aerosol, cloud, radiation and water cycle in the atmosphere” data, in particular data from Earth observation space missions… Indeed, ICARE makes it possible to exploit the huge volume of data available; to combine the various observation data to derive geophysical parameters and to offer easy on-line access to the products.

In this context, ICARE works in collaboration with international space agencies (CNES, NASA, ESA, EUMETSAT, ISRO, etc.) and scientific experts in the field and participates in numerous regional, national and international collaborative projects (GEWEX, CHARMEX, ACTRIS, CCI, GAIA-CLIM, etc.).

Main activities inside AERIS

The main activities carried out by CDS ICARE are :

  • The collection, processing, storage and dissemination of data;
  • The development of data visualisation and analysis tools;
  • The development of operational processing chains;
  • Assistance to users and provision of material resources.
