Air quality today
The air quality in Brockton, Massachusetts is rated as Good today. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 5.5 µg/m³ based on two valid observations reported through OpenAQ.
Overall conditions meet the criteria for the Good category, reflecting low levels of fine particulate matter in the atmosphere. 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 air‑quality dataset for Brockton includes two measured pollutants: ozone (O3) and fine particulate matter (PM2.5). Both are represented by a single monitoring row, so the city’s coverage consists of one station per pollutant. The most recent reading for each comes from 2026‑02‑10 23:00 UTC, meaning the data are fresh within the past week.
For ozone, the only recorded value is 0.03 ppm, which also serves as the minimum, median and maximum across the dataset. This uniform figure indicates that there is no observed variation in O3 at the Brockton sensor during the reporting period. Likewise, PM2.5 shows a single consistent measurement of 5.5 µg/m³, again acting as the sole data point for its range, median and extreme values.
Because each pollutant is captured by just one row, there is no spread or distribution to describe beyond these single‑point figures. The dataset does not contain older, unknown, or missing timestamps; all entries fall into the “updated within 7 days” category, confirming that the available data are recent but limited in spatial and temporal depth. Consequently, while the numbers give a snapshot of current conditions at the specific monitoring location, they do not reflect possible variations across different neighborhoods or times of day in Brockton.
