Air quality today
The air quality in Uliastai today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). A single valid measurement recorded a PM2.5 concentration of 30.01 µg/m³, and no PM10 value is available.
Data are 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 Uliastai air‑quality record consists of four measured pollutants – nitrogen dioxide (NO₂), particulate matter 10 µm or less (PM₁₀), fine particulate matter 2.5 µm or less (PM₂.₅) and sulfur dioxide (SO₂). All data come from a total of two monitoring rows, each representing a single station location. The dataset is uneven in terms of recency: the most recent entry is for PM₂.₅, recorded on 2026‑02‑10 17:08 UTC, while the other three pollutants were last updated on 2019‑12‑31 (NO₂ at 12:00 UTC, SO₂ at 12:00 UTC and PM₁₀ at 00:00 UTC). Consequently, three‑quarters of the measurements are over six years old, leaving only a single fresh observation for this city.
Across the available data the values show no variation within each pollutant. NO₂ is consistently reported as 4.0 µg/m³, PM₁₀ as 34.0 µg/m³ and SO₂ as 15.0 µg/m³, with each metric having identical minimum, median and maximum figures. The PM₂.5 reading stands at 30.01 µg/m³, also without any spread. Because every pollutant has a single recorded value, the dataset cannot illustrate daily or seasonal fluctuations; it merely reflects one point in time for each substance.
The limited number of stations and the predominance of outdated entries mean that the current air‑quality picture for Uliastai is based on sparse information. While the recent PM₂.5 measurement provides a glimpse of present conditions, the older NO₂, PM₁₀ and SO₂ values may no longer represent today’s environment. Users should keep in mind that actual concentrations can differ across neighborhoods and over time, given the narrow spatial coverage and the age of most records.
