French RIs include key structures:

• Sites Instrumentés (SI): regional observatories (e.g. SIRTA in Paris Region)
• Services Nationaux d’Observation: thematic structures that focus on specific variables (e.g CLAP on atmospheric aerosols, COOL on oceanic carbon).
• Instruments Nationaux: 

IPSL contributes to research infrastructures in the domain of Atmosphere, Ocean and Continental Surfaces:

• Atmosphere: ACTRIS, ICOS (observation); CLIMERI (modeling)
• Ocean: OHIS (observation)
• Continental Surfaces: OZCAR (observation)
• Data: DATA TERRA
