Throughout the day, we observed a little amount of PM or at least in little or insignificant amounts as observed in the Copernicus image below (left). The Copernicus image provides us with biomass burning concentration over the nation. A lot of the smoke is coming from southern states like Florida and even smoke has been observed from the Gulf of Mexico and smoke from Cuba traveling North. The HMS image on the right shows the fires seen in the Southeast region of the US. Fires come from agricultural and seasonal fires producing light smoke traveling east but dissipating after less than an hour.
