Air quality today
The air quality in Geneva, Illinois is classified as Good today. The primary pollutant identified is PM10, and the reference value for this metric is 3.5 µg/m³. Six valid measurements were recorded to support this assessment.
Data are shown via OpenAQ and reflect the current monitoring conditions. 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
The Geneva, Illinois dataset draws from five sensor records that together capture five distinct air‑quality variables: PM1 (fine particles), PM2.5 (particulate matter ≤ 2.5 µm), relative humidity, temperature and UM003 (particle count per cubic centimetre). All five pollutants are present in the data, but none of the rows carry a recent timestamp – each entry falls into the “unknown” freshness bucket, meaning the most recent update time is not available.
Across the five observations the measured values show virtually no variation because every pollutant has a single recorded figure. PM1 registers at 1.37 µg/m³, while PM2.5 sits at 4.67 µg/m³; both are reported with identical minimum, median and maximum values. Relative humidity is logged as 58.26 % and temperature as 22.92 °C, again each with a single consistent reading. The UM003 count stands at 334.84 particles per cm³, likewise without any spread.
Because the dataset consists of only five rows and all timestamps are unknown, it provides limited insight into how air quality may change across different neighborhoods or times of day in Geneva. Users should keep in mind that conditions can differ by location and moment, and the current snapshot does not reflect recent measurements.
