Smoke over the Gulf of Mexico; Moderate PM2.5 in California, Great Plains and Great Lakes States

NOAA's HMS product reported the presence of thin smoke in the Gulf of Mexico, extending east from Galveston Bay, TX. This smoke is the cause of the high AOD observed, by MODIS Aqua (top left image) over the Gulf of Mexico. The smoke was produced by fires near Port Lavaca in Calhoun County, TX (fire locations are indicated by red dots in top right image, MODIS Aqua "RGB image"). Size distribution retrievals (bottom left image, courtesy of AERONET) from sun photometer measurements of the coast of Lousiana, reveal the presence of coarse particle pollution in this smoky air mass.

EPA's Airnow AQI animation (bottom right animation) indicate that California, Great Lakes and Great Plains States experienced Moderate PM2.5 concentrations.
