Air quality today
The air quality in Alatri today is classified as Good. The primary pollutant identified is PM10, and the measured concentration aligns with a reference value of 17.0 µg/m³ based on five valid observations.
Data are shown via OpenAQ. 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 Alatri air‑quality record contains data for five measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), the combined nitrogen oxides metric (NOX) and particulate matter up to 10 µm (PM₁₀). The dataset is built from six individual rows, which correspond to two monitoring stations feeding OpenAQ. Freshness varies across the series: the most recent NO₂ reading was logged on 2026‑02‑09 at 03:00 UTC, while CO’s latest entry dates back to 2023‑01‑09 at 09:00 UTC, making it the oldest measurement in the set. The other gases (NO, NOX and PM₁₀) were all updated within the past week, on 2026‑02‑09 or 2026‑02‑08.
Across the five pollutants the observed values are very narrow. CO is reported at a constant 900 µg/m³ in its single row, NO sits at exactly 5 µg/m³, NOX at 27 µg/m³ and PM₁₀ at 17 µg/m³ – each with no variation between minimum, median and maximum. NO₂ shows a slightly broader spread, ranging from 0 µg/m³ up to 19 µg/m³, with a median of 9.5 µg/m³; the 10th percentile sits at 1.9 µg/m³ and the 90th percentile at 17.1 µg/m³. This indicates that, while most pollutants are captured as single static values, NO₂ provides a modest range of recent observations.
Overall, the data set offers limited temporal depth: half of the pollutant rows are very recent, but one key metric (CO) is over three years old, and no entries fall into an “unknown” freshness category. Consequently, while the snapshot gives a clear picture of current concentrations at the two stations, it does not capture longer‑term fluctuations that may occur across different parts of Alatri or over extended periods.

Data notes
The data shown for Alatri reflects five valid measurements and was refreshed within three days, with the latest update recorded at 2026‑02‑09T03:00:00+00:00. These values provide a current snapshot of ambient conditions, but air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in this summary.
