His group is interested using the July 6-8, 2002 Quebec Forest Fire event as a “tracer of opportunity” for evaluating their “CANERM” model. Speaking from “ground zero” (+ about 500 miles), I can report that the smoke plume was not only dense here in Vermont, but also relatively “pure”. That is, there was relatively little other pollution mixed with it. There was also little or no cloud cover on the main impact day here (7/7), which was also a routine 1-in-3, 1-in-6 & 1-in-12 filter & gas canister sampling day, and there were several "intensive" (aircraft & surface-based) measurement campaigns going on regionally. So - spatially dense, highly time-resolved surface measurements like from (many recent) continuous PM-2.5 sites, airport ASOS, shadowband radiometers, etc., detailed chemical speciation data and various satellite images & data should reveal a fairly clear and direct “picture” of the event details. See for example: http://capita.wustl.edu/Databases/UserDomains/SaharaDust2000/ So I’m wondering if there might be a “critical mass” of interest in a collaborative model evaluation exercise? If so, return e-mail or possibly the above-mentioned interactive website would be an efficient way to exchange information. Rich Poirot VT DEC Michel wrote: Rich. I will dig out the data describing the specific scenario (horizontal grid resolution, spatial and temporal characteristic of the source term, etc) that was used for the event and will get back to you. We used the CANERM model (CANadian Emergency Response Model) which is an Eulerian transport and dispersion model used mainly for the long range transport of radioactive tracers and volcanic ash (see the pdf file). We have used it quite successfully in the last little while for other applications such as the long range transport of Asian dust across the Pacific (see an upcoming paper in which my colleague Rene Servranckx is one of the co-author http://www.ametsoc.org/AMS/journal_abstracts/index.html )and large scale forest fires.

Clearly this smoke event could be a unique opportunity for model evaluation, and I would be happy to do whatever I can to assist the process. Here are a few questions: 1. Would you object if I passed your note & animation along to several US colleagues? 2. if that would be OK, could you suggest an appropriate brief description I might use (for example "The attached note and model animation from Michel Jean refers to some preliminary transport & disperson modeling his group at the Canadian Meteorological Center has conducted for the July 02 Quebec forest fire event")? 3. Did you (or can you) make estimates of source emission rates - or did you use some sort of constant "unit" emissions? Rich Poirot VT DEC > Bonjour Rich, > > We have met in RTP about a year ago.
