How Pollen is Counted
We are happy to partner with pollen.com so we can give you a pollen forecast and hopefully some answers to what may be causing your allergies. Pollen is counted by a volunteer force of pollen counters across the country. Each pollen counter has a small box that contains a window and a specialized type of tape. The window in the box opens up and a fan pulls air in and any molecules in the air stick to the tape. The tape is on an automatic roller so new sticky tape is slowly revealed in the window throughout the day. Each day the Pollen Counter removes the previous day's tape and under a microscope counts the different types of pollen. Their counts are then uploaded to the pollen.com website. Today’s results are usually from yesterday's tape counted today. There is a great network of pollen counters in Tennessee that cover Nashville, Brentwood, Franklin, Murfreesboro, and Hendersonville.
