Air quality today

The air quality in Mae Mo is currently assessed as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 concentration of 25.2 µg/m³, based on two valid observations reported through OpenAQ.

No additional pollutants are indicated for today’s assessment. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The air‑quality record for Mae Mo draws on fifteen data rows collected at three monitoring sites and covers six common pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤10 µm (PM₁₀), particulate matter ≤2.5 µm (PM₂.₅) and sulfur dioxide (SO₂). The most recent observations vary by pollutant: the latest O₃ reading comes from 2022‑11‑13 11:00 UTC, PM₁₀ from 2023‑03‑31 23:00 UTC, PM₂.₅ from 2026‑02‑10 22:00 UTC, SO₂ from 2022‑07‑07 09:00 UTC and NO₂ from 2022‑04‑26 04:00 UTC. CO has no timestamp attached, so its freshness cannot be assessed.

Across the five pollutants with timestamps, the data are generally old – most values were recorded more than a year ago, and only PM₂.₅ shows an update within the past week. The range of measurements also differs markedly. Ozone spans from 0.011 to 0.037 ppm, with a median of 0.018 ppm; NO₂ varies between 0.002 and 0.017 ppm, centering around 0.0095 ppm; SO₂ is low, ranging from 0.001 to 0.005 ppm and clustering near the lower end at 0.001 ppm. Particulate matter shows a broader spread: PM₁₀ values run from 6 to 127 µg/m³ (median 16 µg/m³), while PM₂.₅ is tightly clustered between 6 and 25.3 µg/m³ with a median of 25.2 µg/m³, indicating that the highest fine‑particle concentrations recorded are close to the upper end of the observed range.

Because the dataset contains only three stations and many entries are dated or lack timestamps, it provides a limited snapshot of air quality in Mae Mo. Conditions can differ across neighborhoods and over time, so the figures presented here represent specific moments rather than a continuous picture of the city’s atmosphere.

Data notes

The data shown for Mae Mo is based on two valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10T22:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and vary throughout the day, so values may not represent the entire city at all times.
