Fires Blanket Southeastern U.S.

A large number of fires burn in the southeastern quadrant of the Nation. Most of these fires are prescribed or agricultural, and they are producing small plumes of mostly light density smoke as seen in the NOAA HMS image on the top left. The smoke seems to be traveling in a northeasterly direction. Also seen in this image are two large plumes of mostly light smoke produced in Mexico and traveling up to Texas and across the Gulf of Mexico, through the southeast region, and out to the Atlantic Ocean. The VIIRS satellite image , top right, shows a pink cloud over the Southeast which further demonstrates the smoke coverage in the region. All of this smoke affected this area's, as well as the surrounding areas', air quality as the AQI animation on the bottom left shows. Most of the right half of the nation was affected by moderate, code yellow, air quality.

Light smoke seen over Southeast

Air quality today mostly stayed in the Code Yellow (Moderate) levels of PM 2.5, most Code Yellow being seen in the Northern and mid-Plains States, along with some Code Yellow in the Southeast along with the Mississippi Valley (AirNow, left). Smoke continues to accumulate in the Southeast, as seen in NOAA's HMS map, right, but it doesn't seem to have had much of an impact on the PM 2.5 levels in this area.

Fires in Eastern Texas

The overall air quality of the Nation was good today. There were a few sporadic small areas of moderate, code yellow, air quality in California, The Central Plains, and the Northeast, but those can be accredited to local pollution for the most part. In California, small patches of ozone have started to show up again which also affect the poor air quality in the region (AirNow image, left). Easter Texas, Southern Louisiana, and Southern Mississippi show a few fires producing small plumes of light density smoke. These plumes seem to be traveling south and south east (HMS image, right).

Moderate to low level of PM

Today was a nice and clear day throughout the nation. We observed several fires in the Plain States that contributed to some heightened levels of PM in their respective regions. However, the amount of smoke and PM produced was in such an insignificant amount, concentration levels were able to maintain relatively low conditions.

Air quality was good this weekend, the worst was code orange AQI (AirNow, top left) on the southern coast of California. This could be due, in part, to dust in that area (VIIRS image, top right). The source of this dust is unknown. The HMS image (bottom) shows some light smoke plumes in south and central Florida. This smoke is remnant from fires that occurred on Friday.

Smoke raises PM 2.5 levels in Southeastern US

There were Code Yellow (Moderate) levels of PM 2.5 in the mid-Plains States as well as the Mississippi Valley (AirNow, top left). Code Orange (Unsafe for Sensitive Groups) and Code Red(Unsafe) levels were also seen over South Carolina and Georgia. This is most likely due to smoke seen in this area, as seen in NOAA's HMS map, top left. Despite the smoke in this area being mostly light density smoke, the air quality was most likely affected so much because of the slow and stagnant winds over the Southeast area (NOAA, bottom left). The smoke most likely stayed in these areas instead of being blown away by the wind, raising the total amount of PM 2.5 in the area. Finally, the smoke was seen in NASA's MODIS Terra satellite images, bottom right.

Naples Smoke continues East and Perryton Fire produces smokes plumes over lower Plain States

The first image, NOAA HMS, displays smoke plumes over northern Texas and southern Florida and with low level winds in the gulf, the remnant smoke from the Naples Fire spreads northward towards Alabama and Georgia. The Perryton Fire originated in Lipscomb and Ochiltree counties in northern Texas, but the GASP image shows increased AOD southward of the fires, indicating smoke plumes moving south (top right). The AirNow gif (bottom left), shows increased AQI along the Texas/New Mexico border, but this was due to unknown cause of moderate levels of ozone in the region. There were also observed spikes in AQI Wyoming and Michigan but there haven't been any reported active fires in the region.
