U.S. Air Quality

Pretty good air quality across the nation

There are a few stations in the US that have elevated PM today (mostly in TX, OH, FL) but there are no obvious sources seen from space. Much of the country is under cloud and severe flooding is forecast through KY, TN and AL. California has elevated PM near Sacramento but that, too, is under cloud. What looked to be a big smoke plume coming off South Carolina is nothing more than high cirrus clouds. We know that from the temperature of the infrared retrievals.
