Air quality today

The air quality in Kristiansand is classified as Good today. The primary pollutant recorded is PM10, which refers to coarser particulate matter.

Based on two valid measurements, the reported PM10 concentration is 4.168 µg/m³. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Kristiansand’s OpenAQ feed currently includes data for three pollutants: nitrogen dioxide (NO2), particulate matter up to 10 µm (PM10) and fine particulate matter up to 2.5 µg (PM2.5). The dataset is built from five rows of measurements, but only two distinct monitoring stations contribute recent values; the third station provides a single older PM2.5 reading from October 2025. For NO2 and PM10 the most recent observations were recorded on 2026‑02‑10 at 18:00 UTC, while the lone PM2.5 value dates back to 2025‑10‑10 at 07:00 UTC.

The range of values shows a clear contrast between gases and particles. NO2 concentrations span from about 11 µg/m³ up to 38 µg/m³, with a median near 24 µg/m³; the 10th and 90th percentiles are roughly 13 µg/m³ and 35 µg/m³ respectively, indicating most recent readings cluster within that interval. PM10 exhibits a far broader spread: the lowest recent measurement is just over 4 µg/m³, but values climb to more than 1,500 µg/m³, with a median of around 760 µg/m³ and percentiles at roughly 155 µg/m³ (10th) and 1,365 µg/m³ (90th). In contrast, PM2.5 is represented by a single data point of about 4.6 µg/m³, so no distribution can be described for that pollutant.

Overall the dataset leans heavily toward recent NO2 and PM10 observations, both updated within the past week, while the PM2.5 record remains outdated by several months. Because only two stations contribute fresh data, spatial coverage across Kristiansand is limited; conditions can differ in neighborhoods not directly monitored. Users should keep in mind that the available numbers reflect a snapshot from specific sites and times rather than a comprehensive city‑wide picture.

Data notes

The current dataset for Kristiansand includes two valid measurements and is updated within three days, with the latest values recorded at 2026‑02‑10T18:00:00+00:00. These figures represent a snapshot of conditions across the monitoring network and may not reflect short‑term fluctuations or micro‑scale differences in air quality that can occur throughout the city at any given moment.
