Air quality today
The air quality in Zamora today is classified as Good. The primary pollutant identified is PM10, with measurements indicating a concentration of 3.0 µg/m³ based on four valid readings reported through OpenAQ.
Overall conditions meet the criteria for the Good category, and the data set consists of four validated observations. 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 Zamora includes six measured pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10) and sulphur dioxide (SO2). All values come from a single monitoring site, identified as ZAMORA 2, so the coverage is limited to one location within the city.
For CO the most recent record dates back to 2025‑12‑22 08:00 UTC and shows a concentration of 100.0 µg/m³; NO was last updated on 2024‑01‑29 23:00 UTC with a value of 34.0 µg/m³. The remaining four pollutants – NO2, O3, PM10 and SO2 – have timestamps from 2026‑02‑09 15:00 UTC, which is within the last seven days. Each pollutant’s dataset contains only one row, so the reported minimum, median and maximum are identical (CO 100.0, NO 34.0, NO2 11.0, O3 66.0, PM10 3.0, SO2 3.0 µg/m³).
Because the data set consists of a single station and most measurements are either old or represent a single point in time, it provides only a snapshot rather than a comprehensive picture of air quality across Zamora. The recent updates for four pollutants suggest some current information is available, yet the older CO and NO values highlight gaps in timeliness. Consequently, conditions can differ in other parts of the city or at other times, and the present figures should be interpreted as limited to the specific location and moments recorded.
