Expertise and experience of the organization
The Laboratoire de Glaciologie et Géophysique de l’ENvironnement (LGGE) is a joint research unit of the CNRS and Université Joseph Fourrier (Grenoble). The laboratory activities cover several topic including ice cores paleoclimatology, and atmospheric researches in polar and non-polar regions. In this last field over the last years, researches were developed for high altitudes characterisation of aerosols (CARBOSOL program) and evaluation of emission sources and impact in alpine valleys (POVA program).

Role and contribution

Airborne aerosol measurements in WP3 (microphysics and chemistry).

Principal personnel involved
Dr. Jean-Luc Jaffrezo (Ph.D.; Ph.: +33-476824232; Fax: +33-476824201, e-mail: jaffrezo@lgge.obs.ujf-grenoble.fr) is senior scientist at CNRS. He worked for more than 15 years on various aspects of tropospheric aerosols at regional/urban scales. His major field is now chemical characterisation of the organic composition of aerosol in urban and remote areas ; co-author of over 50 peer-reviewed publications in the field of measurements of physical and chemical properties of aerosols, their impact on air quality and the determination of emission sources. He has participated to various EU and national projects over the last 15 years.
