Air quality today
The air quality in Alexandria is classified as Good today. The primary pollutant identified is PM10, and the measured concentration aligns with a reference value of 9.27 µg/m³ based on eight valid observations.
Overall conditions meet the criteria for a Good rating according to the data shown via OpenAQ. 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 Alexandria includes five measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM10) and sulfur dioxide (SO₂). All values come from a total of twelve data rows collected at two monitoring stations, identified as TR‑1. The most recent observations for each pollutant were recorded on 2026‑02‑10 at 19:00 UTC, so the freshest available measurements are less than a week old. Ten of the twelve rows fall into the “updated within seven days” bucket, while the remaining two are older than seven days; none are from today or the past three days.
Across the pollutants the recorded concentrations show very limited variation because each parameter has only a single reported value for the latest timestamp. CO is measured at 300.02 µg/m³, NO₂ at 7.39815 µg/m³, O₃ at 52.44273 µg/m³, PM10 at 9.27222 µg/m³ and SO₂ at 3.69367 µg/m³. For each pollutant the minimum, median and maximum values are identical, indicating that only one recent reading is available per substance. The ten‑day freshness of most rows suggests a reasonably current snapshot, but the two older entries mean that some aspects of the city’s air quality may not be captured in real time.
Because the data come from just two stations, spatial coverage across Alexandria is limited; conditions can differ between neighborhoods and at times outside the recorded moment. The uniformity of the recent values also points to a sparse temporal record – there are no multiple observations to illustrate short‑term fluctuations. Users should keep in mind that while these figures provide an up‑to‑date glimpse of key pollutants, they represent a narrow slice of the city’s overall air quality landscape.
