Smoke increases across the Northwest US
Wildfire activity persisted across parts of the Northwest US today, with GOES-11 Wildfire ABBA indicating a number of active fires in WA, ID, and MT (below, left). The smoke from these fires became rather thick from eastern Washington to western Montana, as seen by the widespread haziness in the MODIS true color imagery (below, right). Not surprisingly, the IDEA products portrayed very high MODIS aerosol optical depth (AOD) values over that region, and the smoke was having an impact on surface air quality across portions of the Pacific Northwest.
