The Laboratoire des Sciences du Climat et
de l’Environnement (LSCE) is a joint research unit from
Centre National de la Recherche Scientifique (CNRS) and Comissariat
à l’Energie Atomique (CEA), two major research
agencies in France. It employs currently 150 people, in the
fields of biogeochemical cycles modelling and observation, past and
future climate studies and isotopic markers in the environment. The
BiogeoCycles research department at CEA-LSCE (staff 80) is active
in the areas of atmospheric composition monitoring, development of
process-based models of carbon cycling over terrestrial ecosystems
and in the ocean, and development of inverse methods to quantify
carbon sources and sinks from atmospheric observations. In
addition, the department is responsible for constructing a
high-precision, CO2 analyzer to be installed onboard of an
Airbus-400 passenger aircraft for systematic measurements as part
of the European CARIBIC project. The BiogeoCycles department is
leading the cooperative development involving several laboratories
in France, of a full-blown carbon-water-energy exchange model
called ORCHIDEE, which can be run both at local and global levels.
This model has specific parametrisations over pasture and cropland
ecosystems and can be run either coupled with an atmospheric model
or forced by input climate and weather data.
Dr. Philippe Ciais is
part of the core team of CarboEurope-IP leading the
„Atmospheric“ component of that project. He studied
theoretical physics at the Ecole Normale Supérieure and
obtained a doctorate in 1991 in isotope glaciology. Appointed
permanent position at LSCE since 1994, he leads the BiogeoCycles
department at LSCE since 2002. Ph. Ciais has over 10 years research
experience in the field of environmental isotope studies, of Carbon
Cycle studies and has contributed to 70 publications in journals
and books. He is member of various international and national
comittees, in particular of the Global Carbon Project
(IGBP-IHDP-WCRP), and chairman of the Integrated Global Carbon
Observing Strategy (IGCO) within IGOS. He coordinates the FP5
European project Aerocarb, and the FP5 project
Tacos-INFRASTRUCTURE, and participates into several other projects
within the CarboEurope Cluster
.Dr. Peter Rayner has over 10
years experience in carbon cycle research. He
previously worked in the areas of climate change and paleoclimate
modelling. Of particular interest to GEMS is his work on the
utility of satellite concentration data in source-sink estimation
and his work in applying variational data
assimilation techniques to the carbon
cycle. He
has authored over 40
papers and is in the top percentile of cited
authors in the Geosciences according to Essential Science
Indicators. He is a member of the Global
Analysis, Integration and Modelling task force
of IGBP and a member of the science team of the
Orbiting Carbon Observatory mission. He has been
the convenor of CSIRO's Biosphere Working group.
In 2001 he was awarded the Priestley Medal for research by the
Australian Meteorological and Oceanographical society.
