The Fairbanks area has seen its share of "Air Quality Alerts" this winter season.
Despite the mild temperatures seen, these inversions have trapped unhealthy air in our atmosphere.
Inversions occur when a layer of cold air is trapped below a layer of warm air.
The State Department of Environmental Conservation issued yet another air advisory this Tuesday afternoon for North Pole and Fairbanks.
The department says that air would be unhealthy for sensitive groups for the next several mornings.
So far, the worst month this year for air pollution was listed as December.
Twenty-five days were deemed unhealthy for sensitive groups in North Pole and 16 days were unhealthy in Fairbanks in that month alone.
