Air quality today

The air quality in Arganda del Rey is classified as Good today.

Measurements from six monitoring stations indicate that the primary pollutant is PM10. The observed concentration of PM10 aligns with a reference value of 1.0 µg/m³, and data are presented through OpenAQ. This assessment reflects the current conditions based on the available observations.

What the data includes

The Arganda del Rey air‑quality dataset contains measurements for four pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter 10 µm or less (PM₁₀). The data come from eleven individual rows that are grouped into two monitoring stations, so each station contributes several observations across the different substances.

For NO₂ the most recent value is 5.0 µg/m³ recorded at Arganda del Rey on 2026‑02‑09 15:00 UTC; the series spans a minimum of 5.0 µg/m³, a median of 5.0 µg/m³ and a maximum of 17.0 µg/m³, with the 10th percentile also at 5.0 µg/m³ and the 90th percentile near 14.6 µg/m³. Ozone shows a current reading of 66.0 µg/m³ (2026‑02‑09 15:00 UTC), ranging from 42.0 to 67.0 µg/m³, median 66.0 µg/m³, and a tight inter‑percentile spread (10th percentile 46.8 µg/m³, 90th percentile 66.8 µg/m³). PM₁₀ is reported at 1.0 µg/m³ (2026‑02‑09 15:00 UTC), with values as low as 1.0 µg/m³ and up to 33.0 µg/m³; the median remains 1.0 µg/m³, while the upper tail reaches 26.6 µg/m³ at the 90th percentile. NO is the only pollutant whose latest entry dates back to 2024‑02‑29 00:00 UTC, showing a single recorded value of 6.0 µg/m³ that also represents its minimum, median and maximum.

Overall, three of the four pollutants have very recent updates – all within the last seven days – indicating fresh coverage for NO₂, O₃ and PM₁₀. In contrast, NO data are older by two years, highlighting an uneven temporal completeness across the set. The range of values is modest for NO₂ and PM₁₀, while ozone exhibits a broader spread toward higher concentrations. Because the dataset derives from only two stations, conditions can differ across other parts of Arganda del Rey or change over time, especially where older measurements dominate.

Data notes

The data shown for Arganda del Rey are based on six valid measurements and were updated within 3 days, with the latest reading recorded at 2026‑02‑09T15:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and change throughout the day, so values may not represent the entire city at all times.
