The station is operational and contributes to the US EPA's Air Quality System (AQS), the national repository for ambient air quality data. The station operates under the regulatory framework of the US Clean Air Act, which mandates monitoring of criteria pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. While specific parameters measured at this site are not detailed, typical stations in the South Coast AQMD network include continuous analyzers for ozone and PM2.5, as well as meteorological sensors. The last reported sample date is September 30, 2025, indicating recent data collection. This station serves the rapidly growing Inland Empire region, which faces air quality challenges due to transportation emissions, industrial activity, and geographic trapping of pollutants. Data from Mira Loma (Van Buren) supports regulatory compliance, public health advisories, and air quality forecasting. The station's location in a residential area provides representative exposure data for local communities.

The Mira Loma area lies in the inland portion of the South Coast Air Basin, where topography and meteorology often trap pollutants, leading to elevated ozone and particulate matter levels. The station's siting in a mixed residential and industrial zone helps capture typical population exposure. Monitoring data from this site contributes to understanding regional air quality trends and the effectiveness of emission reduction strategies under the state's stringent air quality regulations.
