Air quality today

The air quality in Arlington, Texas is classified as Good today. The primary pollutant measured is PM2.5, with a recorded concentration of 6.42 µg/m³ based on six valid observations reported through OpenAQ.

Overall conditions remain within the Good category and the available data show only the fine‑particle measurement for this period. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Arlington air‑quality dataset pulls from OpenAQ and currently contains seven individual rows of measurements collected at two monitoring stations. Six pollutants are represented: ozone (O₃), fine particulate matter (PM₂.5), coarse particles (PM₁), relative humidity, temperature and ultrafine particle count (UM003). The most recent data point for ozone was recorded on 2026‑02‑10 19:00 UTC, making it the freshest entry in the set. In contrast, the PM₂.5 reading is from 2018‑12‑04 16:00 UTC, and the remaining four variables have no timestamp information, so their recency cannot be determined.

Across the available observations, ozone shows a single value of 0.028 ppm at the Arlington Municipal site. Fine particulate matter peaks at 7.1 µg/m³ with a median of 7.01 µg/m³ and a narrow spread between roughly 6.9 and 7.1 µg/m³, indicating limited variability in the recorded sample. The lone PM₁ measurement is 2.61 µg/m³, while relative humidity sits at 48.6 % and temperature at 26.8 °C; both are single‑point values without a reported update time. Ultrafine particle concentration is listed as 309.38 particles/cm³, also from an undated entry.

Because most rows lack recent timestamps, the dataset provides only a snapshot rather than continuous coverage of Arlington’s air quality. Conditions can differ across neighborhoods and over time, so while the numbers give a basic picture of the pollutants measured, they do not capture current or location‑specific variations.

Data notes

The data shown reflects six valid measurements and was Updated today (last refreshed at 2026‑02‑11T00:00:00+00:00). These values provide a current snapshot of Arlington’s air quality, but conditions can differ across neighborhoods and change throughout the day, so this overview may not represent every location or moment within the city.
