Air Quality Data - Unedited Hourly Concentrations
Special status notes:
IMPORTANT EARLY SPRING NOTE: Coarse particles levels will rise near roadways and parking lots as the sand & salt is stirred up by winds or vehicle traffic. This is most likely in the days following a winter storm. Once the sand/salt mixture dries out it is stirred up more easily.
