Partner 6.2 - CNRS-LSCE
de Recherche Scientifique (CNRS)
Laboratoire des Sciences du Climat et de l'Environnement
Expertise and experience of the organization
The Laboratoire des Sciences du Climat et de l'Environnement
(LSCE) is a joint research unit of the CNRS, the CEA and the University of
Versailles St-Quentin. The LSCE (staff 250) is part of the Institut Pierre
Simon Laplace (IPSL). The laboratory activities is divided into three main
broad research topics including Climate, Biogeochemical Cycles, and Geochronology-Geochemistry.
The experience and qualification of LSCE researchers relevant to MEGAPOLIS
comprise a unique expertise in air quality including measurements of trace
gases with a focus on VOC compounds, and of aerosols with a focus on aerosol
optical properties and size-resolved chemical composition. Expertise includes
both ground-based and airborne measurements, and vertical profiling with lidar
systems. The CEA will make available resources for the MEGAPOLI Project, in
terms of unfunded personal contributing to the project. CEA will be represented
in this project by CNRS via clause 10.
Role and contribution
Ground based gas phase and aerosols measurements, airborne
lidar measurements during the dedicated campaign in Paris region in WP3.
Principal personnel involved
Dr. Jean Sciare (CNRS Res. Sci., Team
Leader; Ph.: +33-1-69087967; Fax: +33-1-69087716, e-mail: firstname.lastname@example.org)
- is an atmospheric chemist CNRS, working now at LSCE on the experimental
characterisation of tropospheric aerosols. Following his engineer diploma
in chemistry in 1994, and a 14-month period at Amsterdam Isl. (French Austral
islands) as responsible for atmospheric monitoring activities, he received
PhD (Univ. Paris VII) in 2000 at LSCE on the study of the formation of biogenic
aerosols (DMS cycle) in the Austral Ocean. After a 1-year post-doc at MPI
(biogeochemistry group, Resp. M.O. Andreae), he obtained a permanent CNRS
position at LSCE in 2001. He has participated in many international field
and oceanographic campaigns including BIOGEST, PAURII, MTPII-MATER, MARATHON,
ELCID, LBA-CLAIRE, MINOS, OOMPH. His current activities are focussed on the
study of urban aerosols in megacities (e.g. Beijing, Cairo, Paris) and the
development of techniques to enable in-situ fast and artefact-free measurements
of the main chemical components of sub(super) micron aerosols.
Dr. Valérie Gros (CNRS Res. Sci.; Ph.: +33-1-69087967;
e-mail: email@example.com.) – is an atmospheric scientist at CNRS.
She received her Ph.D. in 1998 at LSCE on the experimental study of ozone
and carbon monoxide at Amsterdam Island (French austral island). Between
1999 and 2004, she worked at the Max Planck Institute for Chemistry in two
different groups (isotope group and organic reactive species group). She
has participated in many international field campaigns including AEROBIC,
MINATROC, UTOPIHAN, HOHPEX, OOMPH and a summer campaign at Amsterdam Island.
She is author or co-author of more than 20 peer-reviewed publications. She
got a CNRS permanent position in 2004 and is now working at the LSCE studying
volatile organic compounds and their impact on the oxidising capacity of
the troposphere and on aerosol formation. She leads the French young researcher
ANR program “AEROCOV”, on interaction of VOCs and secondary organic aerosols
Dr. Bernard Bonsang (Senior Sci.; Ph.: +33-1-69087888; e-mail:
firstname.lastname@example.org) - is researcher at CNRS, is working in the
field of atmospheric chemistry since 1973. His research mainly concerns the
study of the oxidising capacity of the atmosphere with emphasis on the role
of VOCs and related species in the budget of ozone and oxidants. He is graduated
from university of Paris VI (MSc, 1973, and PhD in Nuclear Chemistry, 1974;
and French ‘thèse d’état’ in atmospheric chemistry of sulphur
species, 1980), he has spent a 1 year post doctorate at NCAR (Boulder CO,
USA) He has participated in more than 30 field campaigns over
continental or marine areas. He has been coordinator of EC projects (FIELDVOC,
AEROBIC) and PI of several other national, EU, and international projects
(OCEANONOX, EUROTRAC/ASE, FOS/DECAFE, DYFAMED, TROPOZ, ASTEX/MAGE) in the
field of tropospheric chemistry. His current activities are focussed
on the study of the sources and chemistry of VOCs and related compounds mainly
in remote regions and also over forests and urban areas.
Dr. Patrick Chazette (Senior Sci.; Ph.: +33-1-69089456; e-mail:
Patrick.Chazette@cea.fr) - is a Res. Scientist at the LSCE laboratory since
1993. He has acquired his PhD in the Service d'Aéronomie with Gérard
Mégie in 1990, in the field of space borne lidar dedicated to atmospheric
research. He co-signs more than 40 publications in peer reviewed international
journals and more than 100 presentations in International Symposia. He is
in charge of multi-angular backscatter lidar development for the Commissariat
à l’Energie Atomique (CEA). He is expert on the remote sensing science
for CEA. He previously worked within space borne scientific studies related
to ATLID (1988-1991), ALISSA (1990), BEST (1991-1992) and IASI (1991-1997)
projects. He acted as PI in the international projects MEDUSE (EU project
from 1996 to 1998) and INDOEX (1999). He was coordinator in the frame of
various programs dedicated to air pollution as ESQUIF, POVA and LISAIR. He
is also a member of this scientific French comity and of the “Terre Ocean
Surface Continental Atmosphére” (TOSCA) program for spaceborne-Earth
