This friendly indicator summarizes the latest city readings. For health guidance, please see: EPA AirNow or WHO.
Air quality today
The air quality in Clifton, Arizona is classified as Good today. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 0.0 µg/m³ based on five valid readings reported through OpenAQ.
Overall conditions meet the Good category criteria with no additional pollutants highlighted. 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 Clifton air‑quality dataset draws from a single monitoring row, so the coverage consists of one station reporting five measured variables: PM1, PM2.5, relative humidity, temperature and UM003 (particles per cubic centimetre). All five pollutants have recent data; the most recent timestamp for each is 2026-02-11 01:00 UTC, which falls within the “updated within 7 days” freshness window.
Across the record the particulate matter values are uniformly zero – both PM1 and PM2.5 show a minimum, median and maximum of 0.0 µg/m³, indicating no detected fine particles at the time of measurement. In contrast, the atmospheric conditions show a single consistent reading: relative humidity is recorded at 21.218999894460044 % and temperature at 21.58233331044515 °C, each with identical min‑med‑max values, so there is no observed variability in these parameters for the sampled moment. The UM003 count registers 62.28033345540365 particles/cm³, again without spread.
Because only one row contributes data, the dataset cannot reveal spatial or temporal variation within Clifton; conditions may differ elsewhere in the city or at other times. Nonetheless, the available figures are all fresh (all last updated on 2026‑02‑11) and provide a snapshot of zero particulate matter alongside modest humidity, mild temperature and a moderate particle count for UM003.
