Air quality today

The air quality in Merate today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 26.3 µg/m³ and a PM10 level of 32.2 µg/m³, based on three valid observations reported through OpenAQ.

Data are presented for informational purposes only; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Merate pulls information from eight recorded rows that belong to two monitoring sites. For the city you can see values for nitrogen dioxide (NO2), fine particulate matter (PM2.5), coarse particulate matter (PM10) and ultra‑fine particles (PM1). In addition, relative humidity, temperature and particle count (UM003) are listed, although the latter five have no recent timestamps attached to them.

The most up‑to‑date measurements were all recorded on 2026-02-08 19:00 UTC. On that date NO2 was reported at 35.37378 µg/m³, PM2.5 reached a maximum of 26.3 µg/m³ with a median of 21.9 µg/m³ and values ranging from about 17.5 to 26.3 µg/m³, while PM10 was a single reading of 32.2 µg/m³. These three pollutants therefore have fresh data that is less than a week old.

By contrast the remaining four variables – PM1, relative humidity, temperature and UM003 – lack any timestamp information; their entries are marked as “Update unknown”. Their recorded values are static: PM1 at 11.35 µg/m³, humidity around 57.7 %, temperature about 30.9 °C and particle concentration near 2724 particles/cm³. Because the timestamps are missing, it is not possible to tell when those figures were measured, so they should be treated as less reliable for current conditions.

Overall the coverage is uneven: half of the pollutants have recent, single‑point readings from two stations, while the other half are present only as isolated values with unknown age. This means that city‑wide air quality snapshots are limited to NO2, PM2.5 and PM10, and any interpretation should keep in mind that conditions can differ across neighborhoods and over time.

Data notes

The current dataset for Merate includes three valid measurements and is marked as Updated within 3 days, with the latest values recorded on 2026‑02‑08 at 19:00 UTC. This information reflects a brief snapshot of conditions; air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
