Air quality today
The air quality in Calanda today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Measurements from five valid observations show a PM2.5 reference value of 1.9 and a PM10 reference value of 3.0.
Data are shown via OpenAQ and reflect the current monitoring results for the city. 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 Calanda includes six measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). All values come from a single monitoring station, so the dataset contains one row per pollutant.
The most recent readings are very fresh for five of the pollutants, with the last update recorded on 2026-02-09 03:00 UTC. The NO measurement is older, dated 2024-03-09 23:00 UTC, and is flagged as “Old data”. For each pollutant the reported minimum, median and maximum are identical, indicating that only a single observation is currently available. The recorded concentrations are low and tightly clustered: NO 1.0 µg/m³, NO₂ 3.0 µg/m³, O₃ 71.0 µg/m³, PM₁₀ 3.0 µg/m³, PM₂.₅ 1.9 µg/m³ and SO₂ 3.0 µg/m³.
Because the dataset consists of a single station’s snapshot, it does not capture spatial variation across Calanda and the limited temporal depth means that broader trends cannot be inferred. The uniformity of the values (identical min‑median‑max) shows there is no spread to describe variability at this point. Users should keep in mind that air quality can differ by neighbourhood and time of day, and the current data reflects only one moment from a single location.
