Airborne measurements of particle number concentrations from biomass burning were conducted in the Northern Territory, Australia, during June and September campaigns in 2003, which is the early and the late dry season in that region. The airborne measurements were performed along horizontal flight tracks, at several heights in order to gain insight into the particle concentration levels and their variation with height within the lower boundary layer (LBL), upper boundary layer (UBL), and also in the free troposphere (FT). The measurements found that the concentration of particles during the early dry season was lower than that for the late dry season. For the June campaign, the concentration of particles in LBL. UBL, and FT were (685 +/- 245) particles/cm(3), (365 +/- 183) particles/cm(3), and (495 +/- 45) particles/cm(3) respectively. For the September campaign, the concentration of particles were found to be (1233 +/- 274) particles/cm(3) in the LBL, (651 +/- 68) particles/cm(3) in the UBL, and (568 +/- 70) particles/cm3 in the FT. The particle size distribution measurements indicate that during the late dry season there was no change in the particle size distribution below (LBL) and above the boundary layer (UBL). This indicates that there was possibly some penetration of biomass burning particles into the upper boundary layer. In the free troposphere the particle concentration and size measured during both campaigns were approximately the same. (C) 2009 Elsevier B.V. All rights reserved.
