Air quality today
The air quality in Terrace is rated as Good today. The primary pollutant measured is PM2.5, with a reported concentration of 1.1 µg/m³ based on five valid observations.
No other pollutants reached measurable levels for reporting. 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 Terrace air‑quality dataset includes five measured pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃), fine particulate matter (PM2.5) and sulfur dioxide (SO₂). All values come from a single monitoring location, identified as “TERRACE SKEENA MIDDL”, so the city’s coverage in this set is limited to one station but provides a full suite of common urban pollutants.
Each pollutant has only one recorded value, and that value is identical across its minimum, median and maximum statistics, indicating no observed variation within the available data. NO registers at 0.0003 ppm, NO₂ at 0.0009 ppm, O₃ at 0.022 ppm, PM2.5 at 1.1 µg/m³ and SO₂ at 0.0022 ppm. Because there is a single measurement per pollutant, the spread (10th‑90th percentile) is also the same as the median for every case.
The most recent update for all five pollutants was recorded on 2026-02-10 22:00 UTC, which falls within the “updated within 3 days” freshness bucket. This means the data are current as of today (2026‑02‑12) but reflect only a snapshot in time rather than ongoing trends. With just one monitoring site, temporal and spatial variability across Terrace cannot be captured here; conditions elsewhere in the city may differ from those at the SKEENA MIDDL location.

Data notes
The current air‑quality values for Terrace are based on five valid measurements and were refreshed recently, having been updated within three days (last update: 2026‑02‑10 22:00 UTC). These data provide a snapshot of conditions at the time of collection; however, air quality can differ across neighborhoods and change throughout the day, so local readings may vary from what is shown here.
