Dulac Scripps Institution of Oceanography (SIO) Centre National de Recherches Météorologiques (CNRM) Laboratoire Aérologie (LA) Laboratoire des Sciences du Climat et de l'Environnement (LCSE) Commissariat à l’Énergie Atomique (CEA) funded by the National Science Foundation, INSU-MISTRALS, ANR ADRIMED, Météo France

ADRIMED-ChArMEx Corsica Aerosol Sampling Locations ERSA - Primary ground-based site -Located on Cap Corse peninsula -550 m.asl, ~3 km from ocean -Extensive range of aerosol, trace gas and radiometric measurements Pinerole – Remote mountain site -Located in the island interior m.asl, ~50 km from ocean -Aerosol instrumentation powered by a solar panel array

Portable AERosol Observing System Total Particle Concentration Particle Size Distributions (20 nm – 5 µm) Cloud Condensation Nuclei Supersaturation Spectra (0.7 – 1.5 % Sc) Size distribution Hygroscopicity Aerosol Absorption (black carbon) Meteorology (PTU) Solar flux (  – 0.4 to 1.1 µm) Position, Orientation, Movement

Motivation Identify sources and sinks of aerosol (esp. European emissions, Saharan dust and biomass burning) above the boundary layer Characterize mixing between the free troposphere and boundary layer. Study the evolution of aerosol during transport

Preliminary results Identified dust events, emissions from continental Europe, and biomass burning. Observations at both sites show similar trends; yet with differences that still need to be explored. Strong diurnal variations at Pinerole  transitions between boundary layer and free troposphere Dust events show higher concentrations in free troposphere (esp. 1 um) Transport of black carbon from Europe and biomass burning – concentrations higher in boundary layer
