Shown below is Real-Time output of a Laser Air Particulate Monitor located near St. Joseph’s Hospital in Chippewa Falls, Wisconsin. It is less than 1.5 miles SE of the Plant.
Each reading from a Dylos DC1100 instrument is averaged over five minutes and the graphs are updated every thirty minutes. Large particles (above 2.5 μm) are shown in red while small particles (down to 0.5 μm) are shown in orange. Wind conditions and humidity are collected simultaneously from the weather station at the coordinates 44-52°N 091-29°W. The north (green) and west (blue) wind components are recorded separately and are calculated to provide a true vector average.
