Air quality today
The air quality in Armagh today is classified as Good. The primary pollutant measured is PM10, and the reference value for this particle size is 18.0 micrograms per cubic metre. Two valid measurements were recorded to determine this assessment.
Data are shown via OpenAQ and reflect the current conditions without additional interpretation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The air‑quality record for Armagh currently includes data from a single monitoring location, the “Armagh Roadside” station, which supplies measurements for two pollutants: nitrogen dioxide (NO2) and particulate matter up to 10 µm in diameter (PM10). Because there is only one row of data, coverage across the city is limited to this roadside site.
The most recent NO2 reading was recorded on 2026‑02‑10 at 11:00 UTC, while the latest PM10 value dates from 2026‑02‑05 at 16:00 UTC. Both timestamps fall within the freshness windows defined by the source (within seven days for NO2 and within thirty days for PM10), indicating that the available data are relatively up‑to‑date despite the small number of observations.
All reported values are identical across their statistical summaries, reflecting a lack of variability in this limited dataset. For NO2, the minimum, median, 10th percentile, 90th percentile and maximum are each 26.0 µg/m³. PM10 shows the same pattern with every statistic equal to 18.0 µg/m³. This uniformity means there is no observable spread or range for either pollutant at this site during the recorded periods.
Because only one monitoring point contributes data, the figures represent conditions at that specific roadside location and may not capture differences elsewhere in Armagh. The dataset’s narrow scope and single‑point coverage should be kept in mind when interpreting these numbers as indicative of city‑wide air quality.

Data notes
The current dataset for Armagh includes two valid measurements and was refreshed recently, Updated within 3 days (last update: 2026‑02‑10T11:00:00+00:00). These values represent a brief snapshot of ambient conditions; air quality can differ across neighbourhoods and change throughout the day, so this information may not reflect conditions at every location or time in the city.
