Our mission

ICARE Data and Services Center provides services to the science community to facilitate access to and utilization of satellites and ground-based observations of atmospheric aerosols and clouds properties, water cycle, and radiation. Its mission is to support research studies in atmospheric and climate sciences. ICARE partners with French and worldwide experts in these research fields and with the international space agencies (CNES, NASA, ESA, EUMETSAT, ISRO, etc.).

ICARE is one of the 4 data centers of AERIS, the French Atmospheric Data Infrastructure created in 2014. ICARE contributes to numerous national and international collaborative projects (MACC, IAOOS, ORAURE, ROSEA, CaPPA, GEWEX, CHARMEX, ACTRIS, CCI, AEROCLUB, GAIA-CLIM, …).

ICARE is supported by the CNES and the Hauts-de-France Regional Council as part of a partnership with the University of Lille and the CNRS.
