Air quality today
The air quality in Cranston, Rhode Island is rated as Good today. The primary pollutant identified is PM2.5 (fine particles), with a measured concentration of 4.0 µg/m³. Six valid measurements contributed to this assessment and no PM10 value is available.
Overall conditions meet the criteria for a Good category according to OpenAQ data. 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 data for Cranston includes measurements of black carbon (BC), fine particulate matter (PM2.5), carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO₂) and total oxides of nitrogen (NOX). All six pollutants are represented by a single monitoring station, giving eight rows of observations in total. Freshness varies: six of the rows were updated within the past seven days, while two are older than thirty days, so most of the recent information is less than a week old but a small portion may be out‑of‑date.
Across the pollutants the recorded values are tightly clustered. BC reaches a maximum of 0.41 µg/m³ (near a road) with a median of 0.205 µg/m³ and a minimum of zero, indicating very low variability in recent measurements. PM2.5 is constant at 4.0 µg/m³ for the single reading available, again from a near‑road location. CO, NO, NO₂ and NOX each have one recent value: CO is 0.2 ppm, NO is 0.002 ppm, NO₂ is 0.0101 ppm and NOX is 0.0121 ppm, all recorded at the same timestamp on 2026‑02‑10 23:00 UTC.
The dataset shows uneven depth of coverage: while BC has ten‑percent and ninety‑percent percentiles (0.041 µg/m³ and 0.369 µg/m³), the other pollutants only have a single reported figure, so their spread cannot be assessed. Because the station count is limited to one site, conditions in different parts of Cranston may differ from these values, especially where older rows are involved. Nonetheless, the majority of the data is recent and provides a snapshot of low‑level concentrations for all six listed pollutants.
