Overall conditions meet the Good category criteria with no additional pollutants reported. 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 dataset for Newcastle Parish pulls in real‑time observations from a single monitoring site located in Miramichi. For this city the OpenAQ feed supplies three key pollutants: nitrogen dioxide (NO₂), ozone (O₃) and fine particulate matter (PM2.5). All three measurements are present, each reported with a single value because only one row of data exists for each pollutant. The most recent timestamp across the whole set is 2026‑02‑10 22:00 UTC, which falls within the “last three days” window; in fact every record – NO₂ at 0.0013 ppm, O₃ at 0.039 ppm and PM2.5 at 2.7 µg/m³ – was last updated on that same date and time.
Because there is just one station contributing data, the spatial coverage for Newcastle Parish is limited to the conditions measured at Miramichi. The numeric spread is also minimal: each pollutant shows identical minimum, median and maximum values (NO₂ 0.0013 ppm, O₃ 0.039 ppm, PM2.5 2.7 µg/m³), indicating no variation within the available rows. This uniformity reflects the small sample size rather than a stable ambient environment; conditions can differ elsewhere in the parish or change from hour to hour.
Overall the data are fairly fresh – all entries were recorded less than three days ago – but the dataset is sparse, with only one reporting location and a single observation per pollutant. Users should keep in mind that while these numbers give a snapshot of air quality at Miramichi on 2026‑02‑10, they do not capture broader spatial or temporal fluctuations across Newcastle Parish.

Data notes
The current dataset for Newcastle Parish includes three valid measurements and is marked as Updated within 3 days, with the latest values recorded at 2026‑02‑10T22:00:00+00:00. These figures represent a recent snapshot of ambient conditions but do not capture variations that can occur across different neighbourhoods or times of day within the city. Consequently, actual air quality may differ from what is shown here.
