Parameters Measured

PM-10 (Standard Conditions)

PM-10 (Standard Conditions) is measured in micrograms per cubic meter (25 c).

Coarse particulates (PM-10) come from sources such as windblown dust from the desert or agricultural fields (sand storms) and dust kicked up on unpaved roads by vehicle traffic. PM-10 data is the near real-time measurement of particulate matter 10 microns or less in size from the surrounding air. This measurement is made at standard conditions, meaning it is corrected for local temperature and pressure.
