This is the output of an air particulate monitor (unit A0001) located in
Menomonie, Wisconsin.
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 44.89°N 91.86°W.
The north (green) and west (blue) wind components are recorded
separately and are calculated to provide a true vector average.
