Air quality today

The air quality in Candelaria is currently classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 9.0 and a PM10 reference value of 12.0, based on 17 valid observations collected via OpenAQ.

These values indicate that the monitored particulate levels are within the range associated with the Good category. Data are presented without interpretation or recommendation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Candelaria contains measurements for carbon monoxide, nitrogen oxide, nitrogen dioxide, ozone, PM10, PM2.5 and sulfur dioxide gathered from four monitoring stations across 28 data rows. For most pollutants the newest readings were taken on 2026‑02‑09 at 15:00 UTC, so the dataset is generally fresh, with values updated within the last seven days. The exception is nitrogen oxide, whose latest entry dates back to 2024‑03‑03 00:00 UTC, indicating that this particular series relies on older information.

Across the recent observations the concentrations show a fairly wide spread for some gases and a tighter band for others. Carbon monoxide peaks at 400 µg/m³ while the minimum recorded value is 200 µg/m³, with a median of 250 µg/m³, suggesting that high short‑term spikes are common. Ozone values sit between 90 and 101 µg/m³, clustering around a median of 96.5 µg/m³, which points to relatively stable levels during the latest sampling period. Particulate matter displays lower absolute numbers: PM10 ranges from 7 to 19 µg/m³ (median 13) and PM2.5 from 2 to 9 µg/m³ (median 3.5), indicating modest variability in fine‑particle concentrations.

The dataset also reveals an uneven depth of coverage. While carbon monoxide, ozone, both particulate fractions and sulfur dioxide all have four recent rows each, nitrogen oxide is represented by a single older entry, and the overall count of “old” rows amounts to nine out of 28. Consequently, while the most current snapshot gives a clear picture for most pollutants, gaps remain for NO and for any conditions that may have changed since the last update. Users should keep in mind that air quality can differ across neighborhoods and over time, especially where data are less recent.
