Air quality back to normal after advisory warning Sunday

Advisory due to high levels of particle pollution

La Crosse County’s air quality is back to normal a day after an air advisory warning was issued.

The National Weather Service sent out the advisory because of the high levels of particle pollution in the air.

There are sensors all across the nation that measures these particles every hour during a 24 hour period. Once the levels go above a certain point an advisory is issued.

“It’s largely driven by pollution that is caused by combustion for example from auto mobiles from home heating things like that. Those pollutants then react in the atmosphere and then form fine particles,” said Wisconsin Department of natural Resources Air Programmer Bart Sponseller.

There were elevated reading all across the Midwest yesterday, reaching as far away as Michigan.
