Partner 6.3 - CNRS-LaMP (France)
Centre National de Recherche Scientifique (CNRS)
Laboratoire de Météorologie Physique (LaMP)

Expertise and experience of the organization
LaMP (Laboratoire de Météorologie Physique) is a joint research unit of CNRS and Université Blaise Pascal. LaMP has a long-standing experience in the experimental and modelling studies of clouds and their interactions with solar radiation and atmospheric gaseous and particulate compounds. The main research activities deal with the role of aerosols and clouds in the oxidation capacity of the troposphere and the impact of iced and mixed-phase clouds on the Earth’s radiative budget. LaMP has developed new tools for characterising radiative and chemical properties of aerosols and cloud elements. It implements the cloud observation site of Puy-de-Dôme and manages activities for the French network of free-tropospheric research stations. In addition, LaMP has a long-standing experience with airborne characterization of cloud and aerosol optical, physical and chemical properties. LaMP has co-ordinated a number of EU projects within FP4 and FP5 and is present in the steering committees of several national and international programmes. LaMP is presently coordinating the EUSAAR FP6 Infrastructure program for monitoring of aerosol properties over Europe.

Role and contribution

Airborne aerosol measurements in WP3 (microphysics and chemistry).

Principal personnel involved
Dr. Paolo Laj (Senior Scientist; Ph.: +33-4-43407369; Fax: +33-4-73407382, e-mail: - he has published more than 50 papers in the field of aerosols and clouds and their interaction. He participated in 6 EU project and has procured more than 6 M€ of research income. He is leading the aerosol group at CNRS-LaMP and he is responsible for the French national aerosol program. He is a member of the SSC of the national program for atmospheric research and of the national agency committee for environment and health. He is the scientific coordinator of the EUSAAR I3 project and the coordinator of the action Access to infrastructures within NoE ACCENT.
Dr. Karine Sellegri (CNRS Res. Scientist) - has integrated the Laboratoire de Meteorologie Physique (LaMP), France in October 2004 to study aerosol formation and its physico-chemical properties in natural environments. In the past, she has worked on new particle formation bursts in the Boreal forest (Hyytiälä) in the frame of the QUEST EU project and in the coastal marine environment (Mace Head) in the frame of the BIOFLUX project. Actually, she is involved in EUCAARI and EUSAAR programs.
Assoc. Prof. Alfons Schwarzenboeck (Assoc. Prof. at Univ. of Clermont Ferrand) - he participated to the EU Programs ASTAR, AMMA, and EUCAARI and is involved with the properties of clouds and aerosols and their impact on the Earth radiative balance. He is specialized in airborne operations for sampling aerosols and clouds.
