Pollen counts are determined by counting the number of pollen particles present in a cubic meter of air over a 24 hour period. Counts are classified as Low (0-30), Moderate (31-60), High (60-120), or Extremely High (120+). The table below shows the number of days in which the pollen count was found to be in each category, one spring in Atlanta, Georgia. Note that not all days were measured.
