Agricultural Fires Cause of High AOD over the Mississippi Valley States, Kansas and Oklahoma

The high AOD retrievals (top left image), from NASA's MODIS sensor in Aqua, over the Kansas-Oklahoma border and the Mississippi Valley States is from remnant smoke from agricultural fires over this region. Smoke from the Kansas-Oklahoma agricultural fires is visible in today's MODIS "true color" RGB image (top right). Optical, ground based, sun-photometer AOD taken at the CART site in Oklahoma show how coarse particles are heavily influencing the AOD retrieval has the day progressed.

Ozone concentrations reached Moderate AQI levels (Code Yellow), as shown in today's Airnow Ozone AQI animation, in California, Mid-Atlantic and southern Great Plains states.
