Air quality today

The air quality in Carson, California is classified as Good today. The primary pollutant measured is PM2.5 (fine particles).

Four valid measurements were recorded, with the most recent PM2.5 concentration reported at 6.58 µg/m³. No PM10 value is available for this assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Carson’s OpenAQ feed contains four measured pollutants – PM1, PM10, PM2.5 and temperature – drawn from a total of twenty recent observations across five monitoring stations. The newest timestamp in the set is for PM2.5, recorded on 2026-02-10 23:05 UTC; all other variables were last updated on 2024-04-24 02:05 UTC, so most of the data are several months old while only the fine‑particle measurement reflects a more current reading.

Across the city the observed concentrations span modest ranges. PM1 values range from virtually zero up to 1.77 µg/m³ with a median of 1.39 µg/m³; PM10 varies between 7.5 and 13.85 µg/m³, centering around a median of 9.92 µg/m³; and PM2.5 sits between 3.96 and 9.12 µg/m³, with a typical value near 6.86 µg/m³. Temperature records show a broader spread, from a low of –8.07 °C to a high of 22.34 °C, medianing at 18.16 °C. The 10th‑percentile and 90th‑percentile figures illustrate that most readings cluster toward the middle of these ranges rather than extending to the extremes.

Because only five stations contribute data, spatial coverage is limited; conditions can differ across neighborhoods and times not captured by this snapshot. Moreover, the predominance of “old” timestamps for three pollutants means the dataset does not reflect recent changes in air quality or weather. Users should keep in mind that while the listed values give a baseline picture for Carson, they represent a relatively small and dated sample of the city’s overall environment.

Data notes

The current dataset for Carson includes four valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑10 23:05:54 UTC. These values reflect conditions captured by the monitoring network at that time; however, air quality can vary across different neighborhoods and change throughout the day, so this snapshot may not represent every location or moment in the city.
