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 air‑quality record for Esposende is based on a single monitoring location at Palmeira de Faro, so the dataset contains one row of measurements. All five pollutants tracked by OpenAQ are present: PM1, PM2.5, relative humidity, temperature and UM003 (particle count). The most recent reading for each parameter was taken on 2026‑02‑10 at 22:00 UTC, meaning the data are fresh within the last seven days.
Across the five variables there is no variation in the reported values because only one observation exists. PM1 registers 3.9821666697661082 µg/m³, while PM2.5 shows 11.628666655222574 µg/m³. Relative humidity is recorded at 69.06708323160807 %, temperature at 17.007208426793415 °C and the particle counter UM003 reads 482.9112925211588 particles/cm³. Because each metric has a single minimum, median and maximum that are identical, there is no spread to describe; the dataset therefore provides a snapshot rather than a range of conditions.
With only one station contributing data, coverage across Esposende is limited to this specific site, and any spatial differences in air quality within the city cannot be captured. The timestamps indicate all values are up‑to‑date as of the same moment, but the lack of additional rows means trends over time or comparisons between locations are not available from this source.
