A secured air monitoring station enclosure surrounded by a black chain-link fence topped with razor wire. A sign on the building reads 'Air Monitoring Station,' consistent with environmental air quality monitoring infrastructure typically operated by agencies such as Puget Sound Clean Air Agency near high-traffic or airport zones.

A chain-link fence topped with razor/concertina wire encloses what appears to be utility or communications equipment cabinets, with multiple antennas or sensor masts visible above. The installation is located adjacent to a roadway with a wooded hillside visible in the background, consistent with infrastructure monitoring or navigation equipment near an airport environment.

A chain-link fence with razor wire surrounds a monitoring station enclosure bearing two posted signs. The right sign clearly reads 'Seattle 1st & Weller Air Monitoring Station' and includes logos from Washington State Department of Ecology, EPA Clean Air, and SEPA; the left sign appears to be a multilingual (Vietnamese and Chinese) version of the same information.

A Sound Transit air quality monitoring station enclosure, visible behind a chain-link security fence. A sign on the enclosure reads 'Sound Transit Air Monitoring Station,' and in the background the distinctive roof structure of Lumen Field (Seattle Seahawks/Sounders stadium) is visible, placing this installation in the SoDo/Stadium District area of Seattle.

A small concrete block building enclosed by a chain-link fence topped with razor/concertina wire, with a communications or antenna mast rising from or near the structure.

A sign mounted on a chain-link fence identifies the Seattle 10th & Weller Air Monitoring Station, operated by the Washington Department of Ecology and the Puget Sound Clean Air Agency in cooperation with the EPA. The station monitors nitrogen dioxide, carbon monoxide, and fine particle pollution to determine whether air quality meets national health-based standards.
