MISTRALS: 10 years of multi-disciplinary reserch coordinated at international level to observe and understand the Med. system and forecast the habitability of the region over the centuryChArMEx: one of the 8 topics of MISTRALS (CNRS/INSU) started in 2007 and endorsed internationally
ChArMEx: Chemistry-Aerosol Mediterranean Experiment
Component of MISTRALS about atmospheric chemistry, i.e. the cycle of short-life species (< a few weeks) chemically and optically active in the atmosphere
Why the Mediterranean?
6 – 10 April, 2015 VIII Workshop on Lidar Measurement in Latin America 4/23
Strong accumulation of particles above the Basin

aerosol optical thickness

Why the Mediterranean?
6 – 10 April, 2015 VIII Workshop on Lidar Measurement in Latin America 5/23
A natural laboratory to study:● Contribution of long range transport on the local air quality● Ageing of continental air masses above the Basin● Impact of the atmospheric chemistry on the regional climate● Impact of deposition on waters poor in nutrients
Objectives/WPs of ChArMEx Emissions
Atmospheric processes of reactive gases and aerosols
Impact of long-range and vertical transport on air quality
Radiative budget and climate impact
Atmospheric deposition
Recent trends and variability in trace species
Modelling the future of the Med. atmospheric chemistry
6 – 10 April, 2015 VIII Workshop on Lidar Measurement in Latin America 6/23
ADRIMED SOP-1a 12 June – 5 July, 2013 Western and central Med. Basin 2 supersites 5 secondary sites In-situ, remote sensing instrumentation 2 aircraft Objectives:
● To gather an innovative database of the aerosol physical, chemical, optical properties in order to
1) estimate precisely 1D local direct radiative forcing and constrain 3D regional climate models, and
2) investigate how the modifications of the radiative budget (especially at the sea-surface) due to aerosols affect the sea-surface evaporation fluxes and the Mediterranean hydrological cycle during the dry season

Conclusions A moderate multi-intrusion event has been captured at
EARLINET stations during ADRIMED SOP-1a Larger values of AOD were found over Spain than over
southern Italy The vertical distribution is very similar in both Spanish
sites while it is more heterogeneous over Italy where two intrusions from different origin are observed
Further analysis is needed to differentiate the mineralogy of both dust particles which are mixed
