Air quality today
The air quality in Macerata today is classified as Good. The primary pollutant identified is PM10, with a measured reference value of 3.2 µg/m³ based on four valid observations.
Data are shown via OpenAQ and reflect the current assessment for this location. 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 dataset for Macerata includes five measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), ozone (O3) and particulate matter 10 µm or less (PM10). All values come from a single monitoring location, identified as “Macerata COLLEVARIO”, so the station count is one row per pollutant.
The most recent observations are very fresh for four of the five pollutants, with data recorded on 2026‑02‑07 20:00 UTC. Only NO is older, last updated on 2024‑03‑11 10:00 UTC, which means that for this gas the information is nearly two years out of date while the others reflect conditions from just a few days ago.
Across the pollutants the recorded concentrations are uniform because each metric has only one reported value. CO sits at 200.0 µg/m³, NO at 3.1 µg/m³, NO2 at 15.6 µg/m³, O3 at 67.5 µg/m³ and PM10 at 3.2 µg/m³. Because there is a single measurement per pollutant, the minimum, median, maximum, 10th percentile and 90th percentile are all identical for each substance.
The data therefore give a snapshot rather than a range of variability; there is no spread to describe trends over time or differences between locations within the city. Users should keep in mind that conditions can change across neighborhoods and throughout the day, and the single‑point values may not capture those fluctuations, especially for NO where the last reading is considerably older than the others.

Data notes
The data shown for Macerata are based on four valid measurements and have been updated within 7 days, with the latest refresh recorded at 2026‑02‑07T20:00:00+00:00. This snapshot reflects conditions at the time of sampling; air quality can vary across different neighbourhoods and moments throughout the day, so values may not represent every location or instant in the city.
