Air quality today
The air quality in Acerra today is classified as Good. The primary pollutant measured is PM2.5.
Measurements show a PM2.5 concentration of 7.1 µg/m³ and a PM10 level of 17.44 µg/m³, based on five valid readings. Data are provided via OpenAQ. A total of five measurements were recorded for the pollutants today. PM2.5 refers to fine particulate matter with a diameter of 2.5 micrometers or less. PM10 denotes particulate matter up to ten micrometers in diameter. Both metrics are expressed in micrograms per cubic metre. The five valid readings support the current assessment. 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 Acerra includes five measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂, written as NO2), sulfur dioxide (SO₂), particulate matter 10 µm or smaller (PM10) and particulate matter 2.5 µm or smaller (PM2.5). Altogether there are seven rows of data coming from two monitoring stations: the industrial zone station supplies CO, NO₂ and SO₂ readings, while the school‑site station provides PM10 and PM2.5 values.
All observations were last updated on 2026-02-07 at 07:00 UTC, so the freshest timestamp in the whole set is just a few days old. For each pollutant the most recent measurement is therefore “Updated within 7 days”. CO shows a minimum of 280 µg/m³, a median of 325 µg/m³ and a maximum of 370 µg/m³, with the 10th percentile at 289 µg/m³ and the 90th percentile at 361 µg/m³ – indicating a relatively tight spread around the middle values. NO₂ ranges from 8.93 to 20.45 µg/m³, median 14.69 µg/m³, with the 10‑percentile at about 10.08 and the 90‑percentile near 19.30 µg/m³, showing a broader distribution than CO. SO₂ is represented by a single value of 1.28 µg/m³, as are PM10 (17.44 µg/m³) and PM2.5 (7.1 µg/m³); each of these three pollutants has only one row, so no range or percentile can be derived.
Because the industrial station contributes three rows while the school site provides just two, coverage is uneven across pollutant types. The dataset contains no older or unknown‑timestamp entries, but the limited number of stations means that conditions may differ in other parts of Acerra and at times beyond the most recent snapshot.
