Supplementary Material for paper entitled "Investigation of CO, C2H6 and aerosols in a boreal fire plume over Eastern Canada during BORTAS 2011 using ground-based and satellite-based observations and model simulations" by D. Griffin et al. (citation:  Atmos. Chem. Phys., 13, 10227-10241, 2013 doi:10.5194/acp-13-10227-2013).

This animation (series of images) simulates the motion of the boreal fire plume from its emission in Northwestern Ontario and how it move eastward to the DGS observatory in Halifax, Nova Scotia.  

The file "constant-release.gif" was created by Jason Hopper (hopperj@dal.ca) using FLEXPART forward-trajectories, for a constant particle release starting on 17 July 2011, between 17 July (12:00 UTC) and 23 (00:00 UTC) July 2011 in time steps of 3 h. The colour contours are on a scale from high (red) to low (blue) concentrations.  

FLEXPART is a Lagrangian Particle Dispersion Model, which was developed at the Norwegian Institute for Air Research (Stohl et al. (1998)).
