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 Suyu District air‑quality feed draws from three monitoring rows, each reporting a subset of the ten listed pollutants. Freshness varies markedly: PM2.5, PM1 and relative humidity were last updated on 2026‑02‑10 at 17:00 UTC, while CO, NO₂, O₃, PM10, and SO₂ all date back to 2021‑08‑09 at 11:00 UTC, making the latter five measurements over two years old. For the most recent data, PM2.5 values range from about 6.65 µg/m³ (the minimum recorded at Echo Park Garden) up to 39 µg/m³, with a median of 27 µg/m³ and a 10th‑percentile near 10.7 µg/m³ and a 90th‑percentile around 36.6 µg/m³. PM1 is reported as a single constant value of 2.5858 µg/m³, and relative humidity sits at a single reading of roughly 60 %. The older pollutants show narrower spreads: CO varies between 500 and 700 µg/m³ (median 600 µg/m³), NO₂ stays within 16‑17 µg/m³ (median 16.5 µg/m³), O₃ ranges from 68 to 156 µg/m³ (median 112 µg/m³), PM10 spans 29‑88 µg/m³ (median 58.5 µg/m³), and SO₂ is between 4 and 7 µg/m³ (median 5.5 µg/m³). Because most rows are old, the dataset captures only a snapshot of past conditions; current levels may differ across neighborhoods and times of day. The limited number of stations also means spatial coverage is uneven, with some pollutants represented by just one recent observation while others rely on dated readings from a single location.

Data notes
The current dataset for Suyu District includes five valid measurements and was refreshed recently, with the latest update recorded on 2026‑02‑10 at 17:00 UTC; it is therefore considered updated within three days. While these figures represent the most recent monitoring data available, air quality can differ across neighborhoods and change throughout the day, so conditions may vary from this snapshot.
