The SLO County APCD recently added a mobile monitoring station as well as a mobile solar-power source that can be deployed to charge multiple entities, from the mobile monitoring station itself to plug-in vehicles. There are currently 11 permanent air monitoring stations in the county . The mobile monitoring station gives APCD the opportunity to monitor locations that do not currently have a permanent station close by when there is a change in air quality. The mobile monitor and mobile solar-powered source, secured through grant and settlement funding, have identical equipment to those at a permanent monitoring stations to ensure accurate data collection. The monitoring trailer has two particulate instruments to measure PM 10 and PM 2.5, as well as meteorology tower that measures wind speed, direction and temperature. The solar trailer will give the APCD the ability to take measurements in places where there is no access to power to widen our reach in the county.
