Pollen count

Tree pollen is fine, powdery pollen, making it easy for the wind to carry it for miles.

A pollen count is a measurement of the number of pollen grains in a given volume of air. Pollen counts, and forecasts of pollen conditions, are routinely produced and reported to the public because high aerial pollen concentration is associated with increased rates of allergic reaction for those with conditions such as hay fever and asthma. The pollen counted are usually identified to family ; particularly families with hyperallergenic pollen e. Thunderstorm asthma events as well as mild winters with warmer days lead to increases in pollen counts, [1] while colder winters lead to delayed pollen release.

It is a number on a scale from 1 to , where a low value green colors means good air quality and a high value red colors means bad air quality.

Atmospheric particulate matter PM are microscopic solid or liquid matter suspended in the air. Sources of particulate matter can be natural or anthropogenic. Of greatest concern to public health are the particles small enough to be inhaled into the deepest parts of the lung. They are a mixture of materials that can include smoke, soot, dust, salt, acids, and metals. Particulate matter also forms when gases emitted from motor vehicles and industry undergo chemical reactions in the atmosphere. PM10 is visible by eye as the haze that we think of as smog.
