Description of the organization

The institute LSCE (Laboratoire des Sciences du Climat et de l’Environnement) is a joint research unit of the Centre National de la Recherche Scientifique (CNRS-INSU) and the Commissariat à l’Energie Atomique (CEA), two major funding agencies in France. The LSCE is part of the Institut Pierre Simon Laplace (IPSL) in Paris and covers numerous fields of research related to climate and environment.

Expertise and experience of the organization

The experience and qualification of LSCE researchers relevant to C-Extreme comprises a unique expertise in atmospheric composition monitoring, development of process-based models over land and ocean, and inversion methods to quantify sources and sinks of greenhouse gazes using atmospheric, space-borne, and in-situ observations. The LSCE researchers also played a leading role in the development of Earth System modelling in France, with the LMDZ-INCA chemistry-aerosol transport model and the ORCHIDEE terrestrial ecosystem simulator.

Selected reference projects

The organizational experience of the LSCE in the European research area is reflected through its active participation in several EU funded projects:

The LSCE coordinates GEOMON-IP dealing with ground-based atmospheric observation complementary to satellite, and IMECC and ICOS dealing with infrastructure carbon cycle measurements.

Key scientific / technical personnel

Dr Philippe Ciais is research scientist, currently Assistant Director at the LSCE (Staff 300). He has over 15 years research in the field of Carbon Cycle studies and of environmental isotope studies, and has contributed to 100 publications in peer reviewed journals, including 10 in Science and Nature.
Dr Philippe Peylin is a research scientist working on the Carbon Cycle with a strong expertise in the development of inverse atmospheric tracer models and in the optimization of biogeochemical models.
Dr Soenke Zaehle is a research scientist, expert in modelling carbon, water, and nitrogen fluxes in terrestrial ecosystems. He is coordinating the development of the ORCHIDEE terrestrial model at LSCE.
Dr Eric Dufrêne is a research scientist, expert in ecology and forest studies and he is involved in the development of ORCHIDEE’s forest module.
