Air quality today

The air quality today in Ponferrada is rated as Moderate. The primary pollutant identified for the current assessment is PM2.5 (fine particles).

Measurements recorded from eight valid sampling points show a PM2.5 reference value of 12.0 and a PM10 reference value of 13.0. These figures are presented through OpenAQ data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The OpenAQ feed for Ponferrada includes measurements of carbon monoxide, nitrogen oxide, nitrogen dioxide, ozone, particulate matter ≤10 µm (PM10), particulate matter ≤2.5 µg (PM2.5) and sulfur dioxide from two monitoring stations, providing a total of fifteen recent data points. Freshness varies: nitrogen dioxide, PM10, SO₂, PM2.5 and carbon monoxide were all updated within the last seven days, with their latest timestamps on 2026‑02‑09 15:00 UTC (or 2025‑06‑14 00:00 UTC for CO). Ozone data are older, recorded on 2023‑02‑01 23:00 UTC from a different site (ES1790A), and nitrogen oxide dates back to 2024‑01‑29 23:00 UTC.

Across the recent records, nitrogen dioxide shows a median of 47 µg/m³ with values ranging from 8 to 48 µg/m³, indicating a relatively tight spread around the typical level. PM10 also clusters closely, with a median of 14 µg/m³ and an observed range of 13 to 27 µg/m³; the 10th‑percentile sits at about 13 µg/m³ while the 90th‑percentile reaches roughly 24 µg/m³. Sulfur dioxide remains low, peaking at 7 µg/m³ and centering around a median of 5 µg/m³. Particulate matter 2.5 µg is especially consistent, varying only between 12 and 13 µg/m³ with a median of 12.5 µg/m³. Carbon monoxide displays the widest variability, from 0 up to 19 000 µg/m³, though the most recent reading was 0 µg/m³. Ozone is represented by a single value of 28 µg/m³ and nitrogen oxide by a constant 6 µg/m³.

Because some key pollutants (ozone and nitrogen oxide) rely on older measurements, the dataset does not capture current conditions uniformly across all substances. Consequently, while recent data give a clear picture for NO₂, PM10, SO₂, PM2.5 and CO, the overall view of air quality in Ponferrada is limited by uneven temporal coverage and the small number of monitoring locations.

Data notes

The data shown for Ponferrada is based on eight valid measurements and was updated within 3 days, with the latest refresh recorded at 2026‑02‑09T15:00:00+00:00. This snapshot reflects conditions captured by the monitoring network at that time; air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
