Moderate PM2.5 levels over the Great Lakes, Mississippi Valley, and Mid-Atlantic regions have increased today, peaking around 11:00 AM, as seen in the EPA Loop (top left). These levels of PM2.5 are presumably related to the high levels of sulfate concentration over these three regions, as seen in the NAAPS model (top right).
The HMS KML image (below) shows smoke plumes encompassing most of Northern Canada. The remnant smoke from the Funny River Fire has parted into two large thin smoke plumes, one containing medium level smoke stretching most of the way across Canada.
This bifurcation was presumably created from the counterclockwise cyclonic weather pattern seen in the weather map below (courtesy of The Weather Channel, bottom left). A small cluster of fires was also detected near the Lake Winnipeg region in Canada, mixing with dust (as predicted in the NAAPS model, bottom right). The dust shown in the NAAPS model possibly coincides with the Asian dust picked up by HMS, coming up from NE Montana and into Saskatchewan.
