Air quality today

The air quality in Basauri today is classified as Good. The primary pollutant identified is PM2.5. Four valid measurements have been recorded for the current reporting period. The reference value for PM2.5 is 3.0 µg/m³ and for PM10 is 7.0 µg/m³. These thresholds provide the basis for the overall assessment.

The data are displayed through OpenAQ, which aggregates the four observations used in this evaluation. The observed PM2.5 concentrations align with the 3.0 µg/m³ reference level, and PM10 measurements are considered against the 7.0 µg/m³ benchmark. No other pollutant exceeds the reference criteria in this set of readings. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Basauri air‑quality feed draws from two monitoring stations and contains ten recent measurement rows. Five pollutants are represented: nitrogen monoxide (NO), nitrogen dioxide (NO2), particulate matter ≤ 10 µm (PM10), particulate matter ≤ 2.5 µm (PM2.5) and sulfur dioxide (SO2). Across the whole set, four rows have been updated within the last 30 days while six rows are older than a month, so the overall freshness is mixed. The most recent timestamps are from 2026‑02‑09 15:00 UTC for PM10, PM2.5 and SO2, and from 2026‑01‑28 12:00 UTC for NO2. The NO record is older, dated 2024‑03‑02 23:00 UTC, showing an uneven recency among the pollutants.

Looking at the numbers, NO is constant at 1.0 µg/m³ with no observed variation. NO2 ranges from 15.0 to 20.0 µg/m³, with a median of 17.5 µg/m³ and the 10th‑percentile at 15.5 µg/m³, indicating a modest spread. PM10 values sit between 5.0 and 7.0 µg/m³, median 6.0 µg/m³, and the inter‑percentile range (5.2‑6.8) is narrow. PM2.5 shows the widest variation, from 3.0 up to 13.0 µg/m³, median 8.0 µg/m³, and a 10th‑ to 90th‑percentile span of 4.0‑12.0, suggesting more fluctuation in fine‑particle concentrations. SO2 is confined to 3.0‑5.0 µg/m³, median 4.0 µg/m³, with a tight inter‑percentile band (3.2‑4.8).

These figures illustrate that while Basauri’s dataset covers the key common pollutants, the depth of recent data varies by compound and the temporal coverage is partly dated. Consequently, the recorded conditions represent a snapshot that may differ across neighborhoods and times of day, and users should keep the uneven freshness and limited row count in mind when interpreting the numbers.
