The allergen counts are supplied by allergist Dr. Joseph Leija who goes to the roof of the Gottlieb Professional Building every weekday morning, (during allergy season, April to October) to gather pollen samples. Pollen grains and spores are collected from a cubic meter sample of air and counted under a microscope.
The latest pollen and spores counts are listed to the right in our Twitter feed.
