Pollen Monitoring

Staff collects pollen from the DAQ monitor.

The NC Division of Air Quality (DAQ) operates a pollen sampler at the Laboratory Analysis Branch headquarters on Reedy Creek Road in Raleigh. It is the only pollen sampler in the state currently operated by DAQ.

Note: DAQ does not forecast pollen levels in North Carolina.

Sampling Frequency

DAQ staff analyze a pollen sample under a microscope.

The DAQ pollen sampler is operated annually from late-February through mid-November. The exact season start and end dates fluctuate yearly. 

Samples are collected Monday through Friday, except on state holidays, and represent the pollen count for the previous 24 hours. Each sample is collected for 24 hours, from 9 a.m. to 9 a.m. of the following day. The sampler collects pollen for 1 minute of every 10 minutes.

DAQ laboratory technicians analyze the collected pollen under a microscope and publish a daily report detailing the number of pollen grains counted.

The detailed pollen counting procedure with pictures can be found here(PDF).

  1. Pollen Type: Individual pollen grains can be divided into three different types: grasses, trees, and weeds.
  2. Number of Grains: This number represents the pollen grains counted on the pollen rod for each pollen type.
  3. Severity: DAQ classifies pollen counts as "low", "moderate", "high" or "very high".
  4. Pollen Count: The number of grains of pollen in a cubic meter of air.
  5. Total Pollen Count: The sum of the individual pollen counts for grasses, trees, and weeds.
