Pollen Count
|
The previous
Aeroallergen Network calculations are based on the data (per
cubic meter) reported by all certified counting stations for trees,
grasses, weeds and molds.
- Median or 50th percentile (half of counts are below this point)
- 75th percentile (75% of counts are below this point)
- 99th percentile (99% of counts are below this point)
Based on these calculations, the National Allergy Bureau has set the following definitions
for low, moderate, high and very high concentration levels: |
