Smoke across the North; Fires in the Northwest

The HMS smoke imagery, below left, shows the smoke from the fires that have been burning in the Pacific Northwest and the Northwest Territories over the past several days covering a large portion of Canada, the Great Lakes, the northern Plains, the northern Rockies, and the Pacific Northwest. This shows up in the elevated AOD in these regions, shown in the MODIS Aqua image below right.

Some of the fires in the Pacific Northwest can be seen in the MODIS Aqua imagery below left, with names for some of the larger fires also visible. All the smoke is likely contributing to the poor AQIs in the region, seen in the EPA AQI loop below right.

The NRL NAAPS model projects sulfates along the eastern seaboard and Gulf Coast, which could explain the Moderate AQIs in the Southeast, Mississippi Valley, and southern Plains.
