Air quality today

The air quality today in Skellefteå is classified as Good. The primary pollutant identified is PM2.5. Reference values for the fine particles are 2.94 µg/m³ for PM2.5 and 5.79 µg/m³ for PM10. Six valid measurements were used to determine the category. These figures represent the conditions recorded for the current reporting period. The assessment reflects the air quality status for the date indicated.

Data is shown via OpenAQ. The dataset includes hourly observations from local monitoring stations, aggregated to provide a concise overview. Values are expressed in micrograms per cubic meter. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Skellefteå air‑quality feed contains measurements for four pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO₂), particulate matter 10 µm or smaller (PM₁₀) and particulate matter 2.5 µm or smaller (PM₂.₅). The dataset is built from nine individual rows collected at three monitoring stations across the city. All rows are identified, and none are marked as unknown; six of the rows have been updated within the last 30 days while the remaining three are older records.

Freshness varies by pollutant. The most recent NO₂ value was recorded on 2026‑02‑02 08:00 UTC at the Skellefteå Kv Renen site. PM₁₀ and PM₂.₅ both have their latest observations from 2026‑02‑10 17:00 UTC at the Skellefteå Kv Pantern location. In contrast, the newest NO reading dates back to 2024‑03‑11 12:00 UTC, making it the oldest of the four and indicating a gap of almost two years since the last update for that gas.

Looking at the numbers, NO₂ shows a wide spread: the minimum recorded value is 2.84 µg/m³, the median sits at 180.22 µg/m³ and the maximum matches the median at 180.22 µg/m³, with the 90th percentile also at the maximum. This suggests most recent NO₂ measurements cluster near the upper end of the observed range. PM₁₀ and PM₂.₅ each have a single reported value—5.79 µg/m³ and 2.94 µg/m³ respectively—so no variability can be assessed for these fractions. NO displays a moderate range, from 13.00 µg/m³ up to 64.23 µg/m³, with a median of 38.61 µg/m³ and a 10th‑percentile of 18.12 µg/m³, indicating a broader distribution than the particulate metrics. Overall, the data set provides recent coverage for three of the four pollutants, but the older NO record and the limited number of rows for PM₁₀ and PM₂.₅ mean that city‑wide conditions can differ by location and time.
