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. The facility appears to be adjacent to a busy roadway with overhead power lines and urban buildings visible in the background; no identifying text, logos, or signage are legible in the image.

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.

Street-level view of the intersection of S Weller Street and 10th Ave S in Seattle's Chinatown-International District, showing a fenced air quality or environmental monitoring station with instrumentation tower. The arch of Lumen Field (formerly CenturyLink/Seahawks Stadium) is visible in the background, and bilingual Vietnamese-English street signs are visible on the pole.

Street signs mark the intersection of S Weller St (400 block) and 10th Ave S in Seattle, with bilingual Vietnamese translations reading 'Nam Đường Weller' and 'Đường Số 10 Nam.'

Two aircraft are visible in flight over a hillside urban area with lush green trees. In the foreground is a secured facility with chain-link fencing topped with razor wire, a tall lattice communications or weather monitoring tower with instruments at the top, and what appears to be a partial solar halo phenomenon in the overcast sky.

A wall-mounted equipment setup featuring an Advantech ADAM data acquisition module, a wireless router/gateway device with dual antennas (labeled 'IONIC' or similar), and various coiled cables including Ethernet and sensor wiring. A shelf holds additional networking hardware and a roll of paper towel, with a solar or power inverter unit visible at lower left.

A white instrumentation enclosure/shelter is mounted on a gravel pad outdoors, equipped with two mushroom-cap inlet sampling tubes on top (consistent with particulate matter or air quality monitors), a radiation shield/temperature sensor assembly, a black exhaust elbow, and associated cabling. The setting appears industrial, with graffiti-marked walls and a corrugated metal building visible in the background.

A TSI Integrating Nephelometer (model visible on front panel label) is mounted on a wall inside what appears to be a small environmental monitoring shelter or trailer. The station includes associated gas cylinders, tubing, data acquisition hardware, and climate control equipment, consistent with an ambient air quality or visibility monitoring deployment.

An Ecotech brand air quality monitoring instrument (serial number partially visible as 15-0730) is connected via yellow tubing to an LG through-the-wall air conditioning unit. The setup also includes a gray electrical enclosure with conduit and associated wiring, consistent with an environmental monitoring station installation.
