Air quality today

The air quality in Kopavogur is rated as Good today. The primary pollutant measured is PM2.5, with a reference concentration of 3.9212 µg/m³. This figure represents the fine particulate matter level used for the current evaluation. Twelve valid measurements were recorded for this assessment, providing the basis for the category assignment.

PM10 levels are reported with a reference value of 25.084 µg/m³, indicating the concentration of larger inhalable particles. All concentrations are expressed in micrograms per cubic meter, the standard unit for air quality reporting. Data is shown via OpenAQ. The information reflects the latest snapshot available. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Kopavogur pulls measurements from two monitoring stations, resulting in twelve individual rows that cover six pollutants: nitrogen monoxide (NO), nitrogen dioxide (NO2), particulate matter 1 µm (PM1), particulate matter 10 µm (PM10), particulate matter 2.5 µm (PM2.5) and sulfur dioxide (SO2). For each pollutant there are two recent readings from the same site, Kópavogur Dalsmári, giving a total of four rows that have been updated within the last thirty days, while the remaining eight rows are older than thirty days. The most current timestamps are 2026‑02‑10 16:00 UTC for NO and PM1, and 2026‑01‑24 14:00 UTC for the other four pollutants.

Across the six substances the recorded values span a modest range for gases and a broader spread for particulates. NO varies from 0.77 to 2.26 µg/m³ with a median of about 1.52 µg/m³, whereas NO2 ranges from 0.74 to 7.62 µg/m³ and sits at a median of roughly 4.18 µg/m³. PM1 is low‑level, moving between 0.22 and 0.74 µg/m³ (median ≈ 0.48 µg/m³), while PM10 shows a much wider interval, 6.22 to 25.08 µg/m³, with a median near 15.65 µg/m³. PM2.5 sits between 1.48 and 3.92 µg/m³ (median ≈ 2.70 µg/m³) and SO2 ranges from 2.87 to 3.93 µg/m³ (median ≈ 3.40 µg/m³). The particulate measurements therefore display the greatest variability, especially the larger PM10 fraction.

Because only two stations contribute data, the spatial picture for Kopavogur is limited, and the older timestamps for NO2, PM10, PM2.5 and SO2 mean that those pollutant levels may not reflect the most recent conditions. Users should keep in mind that air quality can differ across neighborhoods and over time, and the available data provide a snapshot rather than a continuous, city‑wide record.

Data notes

The dataset for Kopavogur includes 12 valid measurements and is updated within 30 days, with the most recent data recorded on 2026-02-10 at 16:00 UTC. This snapshot reflects conditions at the time of sampling, but air quality can vary by location and time within the city. Users should consider these factors when interpreting the values.
