CEREA is a joint laboratory combining the Ponts ParisTech school and EDF R&D. It studies the physico-chemical processes of air pollution and of the atmospheric boundary layer as well as data assimilation and inverse modelling in geosciences.

The Paris-Sud Geosciences laboratory (GEOPS) studies the geological processes produced and / or recorded on the surface of the Earth and solid, earthly planets. It studies the characterisation, tracing, measurement and modelling of these interactions in surface and subsurface environments and reconstructions of them in the past.

LATMOS is a research unit that brings together activities previously developed by the Service d'Aéronomie and by more than half of CETP. It is part of the Observatory of Sciences of the Universe at UVSQ.

The TASQ team at the Laboratoire d’Études du Rayonnement et de la Matière en Astrophysique et Atmosphères (LERMA) applies scientific and instrumental skills from the field of spatial observation, including microwave technology at submillimetre level and atmospheric observation using IR spectroscopy. It also has expertise in high precision spectroscopy and the study of molecular processes for atmospheric and planetary applications.

LISA studies the Earth's atmosphere (atmospheric pollution and climate), the interface between exobiology and planetology, and the question of the evolution of matter towards complex organic systems in various planetary environments.

The LMD studies climate, pollution and planetary atmospheres by associating theoretical approaches with instrumental developments in observation and digital modelling. It is at the forefront of research on dynamic and physical processes to permit the study of the evolution and prediction of meteorological and climatic phenomena.

LOCEAN studies the ocean at a wide range of spatial scales including the role of the ocean on climate variability. The laboratory has also recently undertaken studies on the relationships between climate variability and society as they interact in various contexts (agronomy, economy, health).

LSCE strives to understand climate change at all timescales and to predict the upheavals that our planet will face in the coming decades and centuries due to the rapid increase in greenhouse gases.

The METIS joint research unit is governed by Sorbonne University, CNRS and EPHE and has a special relationship with the Centre for Geosciences at Mines ParisTech. METIS studies how continental environments function and the processes that affect the transfer of water, chemicals, nutrients and contaminants in the soil, subsoil and aquatic environments.

The ‘Surfaces & Reservoirs’ team of the Geology Laboratory at ENS The ‘Surfaces and Reservoirs’ team of the Geology Laboratory at ENS has been attached to IPSL since 2020 in an effort to work towards the common goal of achieving a better understanding of the Earth system. The team brings its own set of skills in geosciences, especially in soils and subsoils, including material flows (erosion), carbon, and water.
