Air quality today
The air quality in La Robla today is classified as Good. The primary pollutant measured is PM10, and the latest data show a PM10 concentration of 12.0 µg/m³ based on four valid observations recorded by OpenAQ.
Overall conditions meet the Good category criteria with no additional pollutants highlighted. 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 La Robla air‑quality record consists of a single monitoring station that reports five pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter up to 10 µm (PM₁₀) and sulfur dioxide (SO₂). Because there is only one row in the dataset, coverage across the city is limited to this location.
The most recent measurements are fairly fresh for four of the pollutants, with data logged on 2026‑02‑09 at 15:00 UTC for NO₂, O₃ and SO₂, and at 06:00 UTC the same day for PM₁₀. The NO value is older, recorded on 2024‑01‑30 at 00:00 UTC, so it does not reflect current conditions. All five pollutants show a single reported value, meaning there is no observed range within this station’s record; each has identical minimum, median and maximum values.
Typical concentrations captured by the station are 1.0 µg/m³ for NO, 9.0 µg/m³ for NO₂, 53.0 µg/m³ for O₃, 12.0 µg/m³ for PM₁₀ and 8.0 µg/m³ for SO₂. Because only one measurement exists per pollutant, the spread (10th‑90th percentile) is also a single point, indicating no variability in the reported data set. This lack of variation suggests that the dataset cannot illustrate short‑term fluctuations or spatial differences within La Robla.
Overall, the dataset provides recent snapshots for most pollutants but relies on a solitary monitoring site and contains limited historical depth, especially for NO. Consequently, while the numbers give an immediate picture of measured concentrations at that point in time, they do not capture how air quality may differ across other parts of the city or change throughout the day.

Data notes
The data shown for La Robla are based on four valid measurements and were refreshed recently, being Updated within 3 days; the latest update was recorded at 2026‑02‑09T15:00:00+00:00. This snapshot reflects conditions at the time of collection, but air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the city.
