What the data includes

The air‑quality record for Pozuelo de Alarcón contains data from a single monitoring site that contributed seven rows of observations across four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM2.5). For three of the gases – NO₂, O₃ and PM2.5 – the most recent measurements were taken on 2026‑02‑09, so they are all “updated within 7 days”. The NO data is older, with its last entry dated 2024‑02‑28, which the system flags as old information.

Across the recent dataset the observed values show a narrow spread. NO₂ ranged from a minimum of 8 µg/m³ to a maximum of 11 µg/m³, with a median of 9.5 µg/m³ and the central 80 % of readings falling between 8.3 and 10.7 µg/m³. Ozone values were similarly tight, moving between 55 µg/m³ and 59 µg/m³; the median was 57 µg/m³ and the 10th‑90th percentile band stretched from 55.4 to 58.6 µg/m³. PM2.5 was recorded at a constant 1 µg/m³ for all recent entries, indicating no variation in that short window. The lone NO measurement is a single value of 6 µg/m³.

Because the dataset relies on just one station, spatial coverage across Pozuelo de Alarcón is limited; conditions can differ in other neighborhoods or at times not captured by these rows. Moreover, while three pollutants have fresh data from early February 2026, the NO record is two years old, highlighting an uneven temporal completeness among the measured species.
