Smoke in Idaho, Montana, haze in the east

I found similar conditions today compared to yesterday, primarily lots smoke over the central US, northwest and northeast, and moderate to unhealthy AQ in the eastern half of the U.S and California. This modis RGB (left) shows impressive smoke plumes in Idaho and Montana, were fire activity persists. The GASP AOD (right) was also quite high today over the regions of smoke. The smoke does not appear to be affecting significantly surface AQ over the northwest, where the AQI remains in the green except for one Idaho monitor in the moderate range.
