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.

Thursday's Comments

Along with some bright sunshine and gentle winds the pollen counts in KC Metro area still in high range today. Both Ragweed and Chenopods are very well adapted to the hot temperatures and dry conditions of late summer in the Midwest. We will continue to have high ragweed levels until we get a major rain or some serious cold weather. However, different types of chenopods and many other common weed pollen grains along with some grass pollen are also in the air at this time. Spore count is still in moderate range. The prediction from SkyCast of MARC for today is GREEN (good Ozone level).
