Lower Plains States wildifre spreads Smoke

PM 2.5 levels today stayed around Code Yellow (Moderate) levels today, with most of the PM concentrating around the Mississippi Valley, the Southeast, and California. (AirNow, top left). Some Code Orange (Unsafe for Sensitive Groups) was also located in the mid Plains States. This rise in PM 2.5 was most likely due to smoke from wildfires in the Southern Plains States and the Mississippi Valley, as shown in NOAA's HMS map, top right. One fire in the lower Plains States in the Mallard Fire, which spans over 47,000 acres and counting (InciWeb). The source of this fire is unknown. Some light plumes of smoke in the general Southeastern region could be seen mixed in with cloud coverage in NASA's MODIS Terra images, bottom left. Ozone levels were also around Code Yellow levels today, with Moderate levels of ozone spreading through the Rocky Mountain States, the Pacific Southwest, and the Great Lakes Region.

Moderate levels of PM 2.5 and Ozone

PM 2.5 levels today stayed at Code Yellow (Moderate) levels today, spreading across the Southern Plains States, the Mississippi Valley, the Great Lakes region, and the Mid-Atlantic, along with trace amounts in California (AirNow, top left). The rise in air quality along the East coast was most likely due to smoke from wildfires in the Southeast. The wildfires, along with the smoke from these fires, can be seen in NOAA's HMS map, top right. Light plumes of this smoke could be seen in NASA's MODIS Terra images over the Southeastern region. Ozone levels, much like the PM 2.5 levels, stayed around Code Yellow levels. Ozone was mostly spread around the East coast, the Northern Plains States, and the Pacific Southwest.

PM 2.5 and Ozone levels stay at moderate levels

Air quality today mostly stayed in the Code Yellow (Moderate) levels today, with most of the PM 2.5 seen being located in the Great Lakes region, the Rocky Mountain states, and the Pacific Southwest (AirNow, top left). PM 2.5 levels did, however, rise to Code Red levels (Unsafe) on the border between Idaho and Montana, most likely due to wildfires and smoke in this area, as seen in NOAA,s HMS map, top right. Ozone levels were also relatively low, with only some Code Yellow and Code Orange (Unsafe for Sensitive Groups) being seen in the Pacific Southwest (weather.gov, bottom left). This rise in ozone was somewhat due to high temperatures in this area, with the temperatures rising to the high ninety degrees throughout the day (weather.gov, bottom right).

Smoke from Plains States wilfires spreads to Southwest

PM 2.5 levels were mostly good today, except for in the Pacific Southwest region (AirNow, top left). PM 2.5 levels ranged from Code Yellow (Moderate) levels to Code Red (Unsafe) levels in this region, most likely because of smoke that spread from wildfires in the southern Plains States and Mexico. The layout of the smoke can be seen in NOAA's HMS map, top right. This smoke was also captured in NASA's MODIS Terra images, bottom left. In this image, light plumes of smoke could be seen mixed in with some cloud coverage. Ozone levels were more widespread, with Code Yellow levels appearing in the Plains States, the Rocky Mountain States, and the Pacific Southwest.

PM 2.5 levels rise in the Pacific Southwest

Air quality levels were not very good today, as PM 2.5 levels rose to Code Purple (Very Unhealthy) levels in the Pacific Southwest, along with Code Orange and Code Yellow (Unsafe for Sensitive Groups, Moderate, respectively), (AirNow, top left). There was also a good amount of Code Yellow seen in the Plains States, the Mississippi Valley, the Mid-Atlantic, and the Northeast. This elevated PM 2.5 was due to smoke in these areas from wildfires. A map of the smoke coverage can be seen in the NOAA's smoke map, top right. The smoke was also captured in NASA's MODIS Terra images, bottom left. Ozone levels were also somewhat bad, as there was widespread Code Yellow ozone across the nation, as seen in AirNow's ozone map, bottom right.

Light smoke spreads across eastern shore

PM 2.5 levels were low again today, with only some Code Yellow (Moderate) levels being seen in the Plains States and the Pacific Southwest (AirNow, top left). This low amount of PM 2.5 was despite some small amounts of smoke along the eastern seaboard. There was also some smoke in the Plains States, which may have affected PM 2.5 levels in this area (NOAA, top right). This smoke was somewhat captured in NASA's MODIS Terra images, bottom left. Ozone levels were also mostly low, with Code Yellow levels being seen in the Pacific Southwest, the Great Lakes region, and the Southeast.

PM 2.5 and Ozone levels mostly low

PM 2.5 levels stayed around Code Yellow (Moderate) levels in the Mid-Atlantic and the Great Lakes Region (AirNow, top left). There were very low levels of smoke today, with only some light plumes of smoke appearing in the mid Plains States and the Southeast, so the smoke may have slightly affected the PM 2.5 levels in this area (NOAA, top right). Some light plumes of smoke can be seen in NASA's MODIS Terra images, bottom left. Ozone levels were very low as well, with only some small amount of Code Yellow appearing in the Rocky Mountain States and California.
