Air quality today

The air quality in Salerno today is classified as Good. The main pollutant identified is PM2.5, with a measured reference value of 1.8 µg/m³, while the accompanying PM10 level stands at 7.9 µg/m³ based on five valid observations.

These figures are presented through OpenAQ data for Salerno, Campania, Italy. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Salerno air‑quality dataset currently contains observations for five pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM10) and particulate matter ≤ 2.5 µm (PM2.5). The data come from eight individual rows recorded at three monitoring stations, so the spatial coverage is limited to a handful of sites across the city. All entries have been refreshed within the past seven days, with the most recent timestamp for every pollutant being 2026‑02‑07 07:00 UTC.

Across the available records the measured values show very different patterns. For NO₂ the three rows span from a low of 12.88 µg/m³ to a high of 38.56 µg/m³, with a median of 16.4 µg/m³; O₃ also appears in three rows and ranges from 9.37 µg/m³ up to 37.29 µg/m³, median 23.33 µg/m³. In contrast, CO is reported only once, at a single value of 700.0 µg/m³, while PM10 and PM2.5 each have a solitary measurement of 7.9 µg/m³ and 1.8 µg/m³ respectively. The percentiles reinforce the narrow spread for the particulate metrics (both p10 and p90 equal the single recorded value), whereas NO₂ and O₃ show broader distributions, with their 10th‑percentile values around 13.6 µg/m³ and 12.2 µg/m³ and 90th‑percentile values near 34.1 µg/m³ and 34.5 µg/m³.

Because the dataset relies on a small number of stations, the picture it provides is necessarily coarse. Some pollutants (NO₂, O₃) benefit from multiple observations that capture a modest range of conditions, while others (CO, PM10, PM2.5) are represented by a single reading each, offering no insight into temporal variability. Users should keep in mind that air quality can differ across neighborhoods and over time, and the current snapshot reflects only the locations and moments captured by these limited rows.

Data notes

The data shown for Salerno are based on five valid measurements and have been updated within 7 days, with the latest refresh recorded at 2026‑02‑07T07:00:00+00:00. This snapshot reflects conditions captured by the monitoring network at that time; air quality can vary across different neighbourhoods and change throughout the day, so values may differ from what you experience locally.
