What the data includes
Arlington Heights’ OpenAQ feed currently includes five recorded rows from a single monitoring site, providing data on five pollutants: PM1, PM2.5, relative humidity, temperature and UM003 particles. All measurements were last updated on 2026‑02‑11 01:00 UTC, which falls within the “updated within 7 days” freshness category, so the dataset reflects very recent conditions for each parameter.
The values reported are identical across the minimum, median and maximum statistics, indicating that only one observation is available for each pollutant at this time. PM1 registers at 27.727833334604895 µg/m³, while PM2.5 shows a concentration of 42.16433308919271 µg/m³. Relative humidity is measured at 49.07049986521403 %, temperature at 15.449499988555907 °C and the particle count for UM003 stands at 1445.6751688639322 particles/cm³. Because there is no spread in the data, it is not possible to describe variability or trends from this snapshot alone.
With just one station contributing a single set of readings, coverage across Arlington Heights is limited; conditions can differ in other neighborhoods or at different times of day. The dataset’s freshness is strong—every pollutant has a timestamp from the same recent hour—but the lack of multiple rows means the current picture is narrow. Users should keep in mind that air quality and related environmental factors may vary throughout the city, and additional monitoring would be needed to capture those differences.
