	abstract = {Aerosol fluxes were measured above a mixed forest by Eddy Covariance (EC) with a Fast Mobility Particle Sizer (FMPS) at the Borden Forest Research Station in Ontario, Canada between 13 July and 12 August 2009. Chemically speciated flux measurements were made at a height of 29m at the same location between 19 July and 2 August, 2006 using a Quadrupole Aerosol Mass Spectrometer (Q-AMS). The Q-AMS measured an average sulphate deposition velocity of 0.3mms(-1) and an average nitrate deposition velocity of 4.8mms(-1). The FMPS, mounted at a height of 33m (approximately 10m above the canopy top) and housed in a temperature controlled enclosure, measured size-resolved particle concentrations from 3 to 410 nm diameter at a rate of 1 Hz. For the size range 18 \&lt; D \&lt; 452 nm, 60\% of fluxes were upward. The exchange velocity was between -0.5 and 2.0 mms(-1), with median values near 0.5 mms(-1) for all sizes between 22 and 310 nm. The size distribution of the apparent production rate of particles at 33m peaked at a diameter of 75 nm. Results indicate a decoupling of the above and below canopy spaces, whereby particles are stored in the canopy space at night, and are then diluted with cleaner air above during the day.},
