Pollen/Spore Count
Choose a region, then choose a city in that region. You will see a table of pollen count information for that city. You can also use this site to create a bar chart of the data. Try creating a bar chart of the level of allergens in the city you selected from trees, grasses, weeds, or molds over a 4-week period beginning last month.
