Pollen Count

Laser particle counts are the number of particles per cubic foot divided into 6 different size ranges. A laser beam literally counts the number of such particles as they are sucked past a detector. There is evidence that increased numbers of particles, particularly in the smaller ranges, are associated with heart diseases. That is why we measure it.

Friday's Comments

Even though the oak season is winding down in KC metro area but we still have rather high oak pollen count today in KC metro area that probably mostly flowed by the north wind from Northern region where there are still lots of them. We also have more pine pollen than usual and only a few grass pollens so far in the collection today. Along with walnut, mulberry and many other pollen in the air our pollen count for today remains pretty high range. Spore count is still in low range with good (GREEN) air quality prediction throughout KC metro area.
