Southeast experiences smoke from small wildfires

PM 2.5 levels were high in various areas across the nation today, with Code Yellow (Moderate) levels being seen in the Pacific Northwest, the Pacific Southwest, the Rocky Mountain States, the Northeast, and the Plains States (AirNow, top left). The PM 2.5 in the Southeastern region was due to wildfires in this area, which spread light plumes of smoke across the region, as seen in NOAA's HMS map, top right. These light plumes of smoke were captured in NASA's MODIS Terra images, bottom left.

PM 2.5 levels heighten along the west coast

There were heavy amounts of PM 2.5 along the west coast, with Code Yellow (Moderate), Code Orange (Unsafe for Sensitive Groups), and Code Red (Unsafe) levels of PM 2.5 seen along the west coast, the Rocky Mountain States, and the Great lakes region, as seen in AirNow's PM map, left. However, the excess PM 2.5 was not due to smoke from wildfires, as there was only some smoke seen in the Southeast (NOAA, right). The rise in PM 2.5 was most likely due to people burning wood to keep warm in the winter months.

Fires in the Plain States and the Southeast

Overall, today was a great day in Air Quality news with minimal AOD reported throughout the nation. We did observe a large amount of fires in the Plain States and Southeast regions of the States. However, very low and minimal amounts of PM were produced from these fires. Smoke was seen in South Florida over Lake Okeechobee as seen in the HMS image below (left). AOD trajectories show low concentrations of aerosols from the Southern Plain States moving Northeast towards the Mid-Atlantic region of the nation (VIIRS CONUS, right).

Merry Christmas!

Merry Christmas to all who observe and Happy Holidays! Today was a great day in Air Quality news across the nation. There were no significant amounts of smoke seen throughout the day and minimal fires were observed. Fires in the Southern Mississippi Valley have contributed to low to moderate levels of PM mostly at the origin in Louisiana (HMS, left). Heavy cloud coverage may have blocked Air quality recordings. Air quality maintained none to low concentrations of AOD throughout the day (EOSDIS, right).

Low overall PM 2.5, light PM in California

PM 2.5 levels were very low today, with only Code Yellow (Moderate) levels of PM 2.5 beng seen in the Pacific Southwest and the Pacific Northwest, along with the Northern Plains States and the Great Lakes region (AirNow, top left). There was also some Code Orange (Unsafe for Sensitive Groups) seen in California. This PM 2.5 in California is due to small wildfires in this area. The smoke coverage can be seen in NOAA's HMS map, top right. The smoke in this area could not really be seen due to heavy smoke coverage in the region (NASA's MODIS Terra, bottom left).

PM in the Pacific Southwest

Today was a good day in Air Quality news with very low to moderately dense PM observed throughout the nation (AirNow, top left). Fires in Southern California produced moderately dense smoke that has traveled Southwest into the Pacific Ocean while PM concentrations were most dense at the origin. It is believed that fires in the Northern Plain States and Western Great Lakes regions of the nation may have contributed to the elevated PM in the Mid-Atlantic and Northeast region of the States (HMS, top right). AOD trajectories shows aerosols from the Pacific Northwest and possibly fires in Mexico moving east towards the Mid-Atlantic and Northeast regions of the nation for the course of 48 hours (VIIRS CONUS, bottom).

Low PM and Smoke

Smoke in Southern California is dissipating as PM concentrations are decreasing. No smoke is being produced from recent fires in the region. However, there is light remnant smoke seen about 100 miles west over the Pacific Ocean due to fires earlier last week (HMS left). Fires in the Plain States are producing light density smoke and are contributing to the slight elevation of AOD as seen in the EOSDIS image below (right). No significant quantity of smoke was observed throughout.
