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

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

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
