Air quality today
The air quality in Monte Porzio Catone today is classified as Good. The main pollutant identified is PM2.5. Five valid measurements were recorded. The reported PM2.5 concentration is 0.01950000027815501. The measurement series reflects recent sampling across the city. Values are expressed in the units used by the reporting system.
These data are shown via OpenAQ. No other pollutants have a reported reference value at this time. The dataset includes only the pollutants with sufficient observations, and other metrics are currently unavailable. The information reflects the status at the time of the latest update. 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 Monte Porzio Catone air‑quality feed pulls data from a single monitoring site that has contributed five recorded rows. All five rows are flagged as “old,” with the most recent measurement timestamped 2026‑01‑24 12:00 UTC for every pollutant. Because the dataset contains only one station, spatial coverage across the municipality is limited to the conditions measured at that specific location.
The available pollutants are PM1, PM2.5, relative humidity, temperature and UM003. For PM1 the recorded value is 0.0 µg/m³, and because the minimum, median and maximum are identical there is no observed variation in the data. PM2.5 shows a constant reading of 0.01950000027815501 µg/m³ across all rows, again with no spread. Relative humidity is fixed at 66.52016696929932 % and temperature at 14.211833254496256 °C, each reported with the same single figure for every entry. The UM003 particle count is consistently 105.08883336385092 particles/cm³, with no deviation between the recorded observations.
These numbers illustrate that the dataset is uniformly static: every pollutant has the same minimum, median and maximum, indicating that the five rows capture essentially a single snapshot rather than a range of conditions. The reliance on one station and the age of the latest timestamp mean the data may not reflect current or location‑specific air quality in Monte Porzio Catone. Users should keep in mind that actual conditions can differ across neighborhoods and over time, and that more recent or additional monitoring points would be needed for a fuller picture.
