Smoke blowing off of West Coast; elevated AOD in Texas


Looking at the NOAA HMS Smoke and Fire Product (top left), the small red dots indicate clumps of fires in the Southeast while the grey areas indicate smoke plumes off of the coast of Oregon and Northern California. This plume is a mixture of smoke from fires in the area as well as blowing dust from Nevada like yesterday as well as Goose Lake along the California/Oregon border. The MODIS Terra AOD animation shows elevated AODs in the area of this plume as well as off the coast of the Southeast corresponding to the fires seen in the HMS. Furthermore, increased AOD is seen along the Texas/Mexico border.

The left photo is form the webcam located in Big Bend National Park, near the Sierra del Carmen in Mexico. As of 3:00 EST (2:00 CST), the AOD has affected air quality and visibility, with a visual range of 115 miles, as compared to the clear/hazy figure to the right.

The EPA AIRNow combined AQI loop (bottom left) did not see much elevations in AQI today in Texas as a result of this, however. The current high AQI is in Stockton. CA (161), as AQIs ranging from moderate to unhealthy have been seen across the West Coast. Only a small area of moderate AQIs was seen in the vicinity of the fires in the Southeast.
