Air quality today
The air quality in Cedar County, Missouri is classified as Good today. The primary pollutant identified is fine particulate matter (PM2.5), based on a single valid measurement reported through OpenAQ. The observed PM2.5 concentration aligns with the reference value of 2.2 µg/m³.
No additional pollutants reached reporting thresholds, and the available data reflect only this one measurement for the current period. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
Cedar County’s public air‑quality feed draws from two monitoring sites that together contribute four data rows, covering the two pollutants tracked for this location: ozone (O₃) and fine particulate matter (PM₂.5). The ozone record comes from a single sensor at El Do Springs and is dated 2025‑11‑04 15:00 UTC, which the system flags as “old data.” In contrast, the PM₂.5 reading also originates at El Do Springs but was recorded more recently on 2026‑02‑10 23:00 UTC and is classified as updated within the last seven days.
The ozone values in the dataset range from a low of 0.04 ppm to a high of 0.047 ppm, with a median of about 0.0435 ppm. The 10th percentile sits at roughly 0.0407 ppm and the 90th percentile near 0.0463 ppm, indicating that most measurements cluster tightly around the middle of the observed spread. For PM₂.5, concentrations vary between 2.2 µg/m³ and 10.8 µg/m³, with a median of 6.5 µg/m³. The lower decile is about 3.06 µg/m³ while the upper decile reaches roughly 9.94 µg/m³, showing a broader distribution than ozone but still within a modest range for this small community.
Because only two stations contribute data, coverage across Cedar County is limited and uneven: ozone information is relatively stale, whereas PM₂.5 reflects a more current snapshot. Users should keep in mind that conditions can differ by neighborhood and time of day, and the available measurements represent a narrow slice of the city’s overall air quality picture.

Data notes
The data shown for Cedar County reflects a single valid measurement and is Updated within 3 days, with the most recent reading recorded on 2026‑02‑10 at 23:00 UTC. This snapshot provides a brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
