LaMP research activities:
The main research activities deal with the role of aerosols and clouds in the oxidation capacity of the troposphere and their impact on the Earth’s radiative budget. Marine aerosols contribute significantly to the global aerosol load, thus having an important impact on both the Earth’s albedo and climate. In this context, LaMP has developed new tools for characterising radiative and chemical properties of aerosols and cloud elements. It implements the aérosol-cloud observation site of Puy-de-Dôme and manages activities for the French network of free-tropospheric research stations.
Objectives of the LaMP experiment during MedSea:
The Mediterranean Sea might produce a primary aerosol which is significantly different from the one produced over the Atlantic ocean. On one hand the phytoplanctonic activity is lower than in the Atlantic Ocean, one the other hand the amount of pollutants injected in the Mediterranean Sea through rivers and atmospheric depositions are higher and might involve higher concentrations of artificial surfactants. The main objective of this experiment is to provide a sea-to-air chemical and physical flux of the aerosol which will be representative of the Mediterranean sea. How this flux might evolve with the impact of climate change on CO2 concentrations in the future will be a new, original and important output from the experiment.
The LaMP team:
She is the scientist in charge for the LaMP experiment, she has studied marine aerosol production from the Atlantic Ocean in C. O’Dowd group (NUIG, Ireland) in the past before integrating the CNRS at LaMP, both when they are produced from primary sources (Sellegri et al. 2005) and from secondary sources (Sellegri et al.). She continued characterizing marine aerosol sources at LaMP and in particular its hygroscopic properties (Sellegri et al. 2008).
What she is expecting from MedSea mesocosm experiment: unique fluxes data which have never been quantified from the mediteranean sea, in combination with the very rich information on the sea water bio-geo-chemical characterization that will come out of the varied and complementary scientific consortium of this experiment. Great ideas and findings from interdisciplinary and international discussions.
She is a post-doctoral researcher in LaMP and coming from Finnish Meteorological Institute in Helsinki. She has worked with atmospheric aerosols since year 2003. Her main interests are experimental studies of natural particle production and aerosol-cloud interactions. She made her PhD thesis year 2010 in Helsinki University on the topic of secondary particle formation. During her post-doc year in LaMP, she has studied marine and continental boundary-layer as well as free tropospheric aerosol properties, and processes of secondary particle formation and particle in-cloud activation. She is looking forward for meeting new people, for fascinating discussions and for great scientific findings during MedSea mesocosm project.
