Fires in Nevada, Smoke over Central U.S.

The EPA AQI loop, below left, shows areas of Moderate AQI across the Mid-Atlantic, Southeast, Great Plains, Rocky Mountains, and Pacific Southwest, with spots of Unhealthy for Sensitive Groups in the southern Plains, the Rocky Mountains, and Pacific Southwest. The HMS imagery, below right, shows smoke over the Rocky Mountains and Plains States from fires in Nevada and the Utah border, as well as a large swath from both these fires and those in the Northwest Territories stretching from the southern Plains through the Great Lakes region on into Canada.

MODIS Aqua caught the smoke coming from the Bear Trap and Hampton fires in Nevada, in addition to a few clouds and their shadows, seen in the Google Earth image below.

The NWS air quality guidance below indicates that a combination of dust and ozone might be responsible for the elevated AQIs in southern California.
