Dusty Day

Strong winds in Utah stirred up a lot of dust

 Wind speeds for time picture was taken

There is a spike in PM 2.5 at the time the winds pick up...

Even ozone pollution reached high levels exceeding NAAQS in a few locations.

Yesterday ozone roses at NAA and MtMet. 

 

Wind Roses speed

 


And just for fun... that bright "star" below the moon is really Mars
