NOAA's Hazard Mapping System (HMS, top left) reports that much of the Mid-Atlantic, Southeast, Mississippi Valley, and Great Lakes Region is blanketed in smoke. These states include New York, Pennsylvania, New Jersey, Delaware, Maryland, Virginia, West Virgina, North Carolina, South Carolina, Georgia, Alabama, Mississippi, Arkansas, Missouri, Tennessee, Kentucky, Ohio, Indiana, and Illinois. In the regions blanketed in smoke, the MODIS Terra AOD map (IDEA, top right) shows moderate to high AOD values. The highest AOD values are observed over North and South Carolina, Maryland, Pennsylvania, and the southern portion of New York. PM2.5 levels (bottom left, courtesy AIRNow) in the regions blanketed in smoke were mostly Code Yellow (Moderate) throughout the day. An area in Pennsylvania reported Code Orange (Unhealthy for Sensitive Groups) PM2.5 levels through much of the night.
Else where in the country, HMS reports fires and smoke in Louisiana, North Dakota, and South Dakota. High AOD values were observed over Montana, Wyoming, Idaho, Washington, Oregon, California, and Nevada. PM2.5 levels in these areas were Code Green (Healthy) for the most part, with exception to Code Yellow reported in southern California. Ozone levels (bottom right, courtesy AIRNow) were mostly Code Green throughout the country for most of the day. However, after noon ozone levels across the south rose to Code Yellow levels, with Code Orange levels reported in Georgia and Alabama.
