This is a plot of the particulate matter(PM)also called aerosols in the air at my site. The sensor measures three size ranges of particles. PM 1.0 Particles smaller than 1 micrometer in diameter, PM 2.5 Particles smaller than 2.5 micrometers in diameter PM 10 Particles smaller than 10 micrometers in diameter. The readings are in micrograms per cubic meter.

In the plot black is PM 10, green is PM2.5 and Red is PM 1.0.
