Air quality today

The air quality in Launceston today is classified as Good. The primary pollutant identified is PM2.5 (fine particles). Current measurements show a PM2.5 concentration of 3.97 µg/m³. This value is expressed in micrograms per cubic metre and is derived from the five valid observations recorded. No other pollutant was highlighted as primary in the current dataset.

All data are presented through OpenAQ, and no PM10 measurements are available for this period. The five valid samples provide the basis for the reported concentration. The Good classification aligns with the measured PM2.5 level. No additional pollutant information is reported at this time. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Launceston air‑quality feed contains six measured variables – PM1, PM10, PM2.5, relative humidity, temperature and the particle count UM003 – drawn from twelve recent data rows that originate at four monitoring sites. For each pollutant the dataset records a single most‑recent value together with basic statistics (minimum, median, maximum and the 10th and 90th percentiles) that describe the range of observations across the rows. PM10 values span from 1.0 µg/m³ up to 6.0 µg/m³ with a median of about 4.34 µg/m³; PM2.5 ranges from 1.0 µg/m³ to 3.97 µg/m³ and sits at a median of 1.5 µg/m³; PM1 is represented by a single reading of 2.43 µg/m³. Relative humidity, temperature and UM003 each have one recorded point – 58.77 % humidity, 21.07 °C temperature and 606.84 particles/cm³ – all measured at the same Frankland site.

The timestamps show a mixed picture of freshness. The most recent PM10 entry dates to 2025‑11‑27 12:54 UTC, which falls into the “old” category, while the remaining five pollutant readings were all logged on 2026‑02‑10 22:00 UTC, placing them within the last three days. Overall, five of the twelve rows are recent and seven are classified as old, meaning that the current snapshot leans heavily on data that is several months out of date for PM10 but is up‑to‑the‑minute for the other parameters. This uneven timing, combined with the limited number of stations, indicates that the dataset provides a concise but not fully comprehensive view of air quality across Launceston; conditions can differ between locations and over time, and the available numbers reflect the specific moments when each sensor last reported.
