Air quality today
The air quality in Erlin Township is currently classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 24.0 µg/m³ and a PM10 level of 55.0 µg/m³, based on six valid observations collected through OpenAQ.
These values reflect the present conditions without implying any trend or cause. 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 air‑quality record for Erlin Township currently includes six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). All of these come from a single monitoring location identified as 彰化縣 – 二林, so the dataset consists of six rows, one for each pollutant.
Each pollutant has a single reported value that also serves as its minimum, median and maximum because only one measurement is available. CO registers at 0.4 ppm, NO₂ at 0.019 ppm, O₃ at 0.005 ppm, PM₁₀ at 55.0 µg/m³, PM₂.₅ at 24.0 µg/m³ and SO₂ at 0.001 ppm. The lack of spread means the data cannot illustrate any range or variability for Erlin Township; it simply reflects the most recent snapshot captured on 2026‑02‑10 23:00 UTC. Because all timestamps fall within the “updated within 7 days” freshness bucket, the information is relatively current, but the single‑point nature limits insight into day‑to‑day changes.
In practical terms, the dataset provides a complete set of common air‑quality indicators for Erlin Township, yet it represents only one monitoring site and one moment in time. Consequently, while the values are fresh, they do not capture spatial or temporal diversity across the township. Users should keep in mind that conditions can differ elsewhere in the area or at other times, and additional measurements would be needed to describe broader patterns.

Data notes
The current dataset for Erlin Township is based on six valid measurements and was refreshed recently, with the latest update recorded at 2026‑02‑10T23:00:00+00:00 (Updated within 3 days). This snapshot reflects conditions at the time of collection; however, air quality can differ across neighborhoods and change throughout the day, so values may not represent every location or moment in the township.
