Air quality today

The air quality in Almassora today is classified as Good. The main pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 4.0 and a PM10 reference value of 7.0, based on six valid observations recorded by OpenAQ.

Overall conditions meet the criteria for a Good rating according to the available data. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Almassora air‑quality dataset contains measurements for seven pollutants – carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter 10 µm or less (PM₁₀), particulate matter 2.5 µm or less (PM₂.₅) and sulphur dioxide (SO₂). All values come from a single monitoring site, ALMASSORA‑C. P. OCHANDO, which contributes seven rows of data to the OpenAQ feed for the city.

The timestamps show that most of the pollutants have been refreshed very recently: CO, NO₂, O₃, PM₁₀, PM₂.₅ and SO₂ were all last updated on 2026‑02‑09 at 15:00 UTC, which falls within the “updated within 7 days” freshness bucket. The only exception is NO, whose most recent reading dates back to 2024‑01‑16 at 22:00 UTC and is flagged as old data. Because the dataset consists of a single monitoring location, there is no spatial variation captured across Almassora; conditions can differ in other neighbourhoods or at different times of day.

Across the six pollutants with recent updates, each shows an identical minimum, median and maximum value, indicating that only one measurement per pollutant is currently available. CO registers 200 µg/m³, NO records 6 µg/m³ (the lone older entry), NO₂ stands at 9 µg/m³, O₃ at 48 µg/m³, PM₁₀ at 7 µg/m³, PM₂.₅ at 4 µg/m³ and SO₂ at 3 µg/m³. The lack of multiple observations means there is no observable spread or percentile range for any pollutant; the reported 10th and 90th percentiles match the single recorded value. Consequently, while the data are fresh for most compounds, the limited coverage – both in terms of geographic reach and temporal depth – should be kept in mind when interpreting air‑quality conditions for Almassora.

Data notes

The data shown for Almassora are based on six valid measurements and were updated within 3 days, with the latest refresh recorded at 2026‑02‑09T15:00:00+00:00. This snapshot reflects conditions at the time of sampling; air quality can vary across different neighbourhoods and change throughout the day, so values may not represent every location or moment in the city.
