Monitoring of ozone, ozone precursors, aerosol mass and aerosol microphysical properties over metropolitan Detroit

Pm sensor over Wayne State

We have installed the PurpleAir sensor over the roof of Engineering Building at Wayne State University in mid-town Detroit for continuous monitoring of PM2.5 concentrations and meteorological conditions since 2020. The forward facing of PurpleAir sensor is the downtown of Detroit. The real-time air quality data can be accessible at https://www.purpleair.com/map?opt=1/mAQI/a10/cC0#11.46/42.3585/-83.0615

Advanced instruments in fields

In-situ measurements of nitric oxide (NO), nitrogen dioxide (NO2), nitrogen oxides (NOx), ozone, aerosol mass and aerosol microphysical properties (e.g., aerosol size and number).

PM SENSOR OVER SOUTHWEST DETROIT

The PurpleAir sensor is collocating with the US EPA PM instrument (managed by Michigan Department of Environment, Great Lakes and Energy) at the southwest (SW) of Detroit for calibration. SW Detroit is considered the most polluted regions within the metropolitan Detroit, with pollution sources from power plant, petroleum, and wastewater treatment plant.
