AB: The Arctic Boundary Layer (BL) is investigated in connection with filamentary propagating smoke plumes during a period of regional haze in the summer 2005, June 29-30. A description of dynamical exchange mechanisms leading to mixing processes taken place in the continental BL is given during a smoke episode from forest fires originated in the North Eastern part of Alaska responsible for high concentration of fine particle matter in the surface. A discussion of the aerosol concentration exchanges during the BL cycles is given based on the time- height eye-safe optical reflectivity signature, surface fine particulate matter (PM2.5), mesoscale WRF modeling, meteorological and satellite information. The interaction between filamentary smoke plume propagation, the morphology of the boundary layer and the surface particle matter is assessed.
