With all the recent wildfires and extreme poor air quality we all experienced around the city, the Facilities department installed a PurpleAir device at the Terra Linda pool area in order to monitor the air quality. A PurpleAir device has “sensors that measure airborne particulate matter. Particulate matter describes solid particles suspended in air; this includes dust, smoke and other organic and inorganic particles. It joins our other PurpleAir device installed at City Hall.
