Air quality today

The air quality in Avellino today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 18.09 µg/m³ and a PM10 level of 4.79 µg/m³, based on ten valid observations recorded by OpenAQ.

These values reflect the current monitoring snapshot for Avellino, Campania, Italy. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Avellino air‑quality feed contains eight measured variables – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter of three size fractions (PM1, PM2.5 and PM10), relative humidity and temperature – collected from three monitoring sites across the city. In total there are eleven data rows representing the most recent observations for each pollutant at those locations.

All timestamps are fairly fresh: the newest readings were recorded on 2026‑02‑10 at 21:00 UTC (PM2.5, PM1, relative humidity and temperature), while the remaining pollutants were last updated on 2026‑02‑07 at 07:00 UTC. No data rows are marked as old or unknown, so the current snapshot reflects conditions measured within the past week.

The dataset shows a narrow spread for some gases but a broader range for particulates. NO₂ values vary only between 2.54 and 2.92 µg/m³, with a median of 2.73 µg/m³, indicating very consistent measurements across the two stations that report it. By contrast, PM2.5 spans from 2.13 to 18.09 µg/m³, with a median of about 10.11 µg/m³, highlighting greater variability in fine‑particle concentrations between the city centre and other sites. CO is reported as a single value of 480 µg/m³ from the Avellino Scuola Alighieri station, while O₃, PM10 and PM1 each have one recent observation (27.45 µg/m³ for ozone, 4.79 µg/m³ for PM10, and 9.62 µg/m³ for PM1).

Because the number of rows differs by pollutant – some have two recent entries while others have only one – coverage is uneven across the suite of measurements. Consequently, while the data give a timely picture of air quality at specific points, conditions can still vary elsewhere in Avellino and over shorter time intervals not captured in this snapshot.
