Air quality today

The air quality in Melilla is classified as Good today. The primary pollutant measured is PM2.5, with a reported concentration of 2.73 µg/m³, while the accompanying PM10 level stands at 21 µg/m³. A total of 29 valid measurements were used to determine these values.

Data are shown via OpenAQ and reflect the current assessment for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Melilla pulls measurements from three monitoring sites and contains a total of thirty individual records. All ten pollutants tracked by the OpenAQ network are represented: carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter in three size fractions (PM₁, PM₂.5, PM₁₀), relative humidity, sulfur dioxide (SO₂), temperature and a miscellaneous variable labelled UM003. The most recent observations were recorded on 2026‑02‑10 at 16:00 UTC for the finer particles, humidity and temperature, while the coarser suite of gases and larger particles was last updated on 2026‑02‑09 at 15:00 UTC (or 03:00 UTC for PM₁₀). This means that the freshest data are no older than two days, although a small number of rows are flagged as “old” in the source metadata.

Across the pollutants the recorded values show a modest spread. CO ranges from 70 to 170 µg/m³ with a median of 125 µg/m³, while NO₂ varies between 0.4 and 6.6 µg/m³ (median 2.85 µg/m³). Ozone is tightly clustered around 75–76 µg/m³, and SO₂ stays within a narrow band of 2.1 to 2.8 µg/m³ (median 2.6 µg/m³). Particulate matter shows the widest relative variation: PM₁₀ spans 3.7 to 21 µg/m³ (median 18 µg/m³), and PM₂.5 from 2.73 to 13 µg/m³ (median 10 µg/m³). The single‑point measurements for PM₁ and relative humidity are both exactly 1.2333333325882752 µg/m³ and 60.56316655476889 % respectively, reflecting the limited sampling frequency for those parameters.

Because the dataset includes only three stations, spatial coverage is limited and conditions can differ across neighborhoods or micro‑environments that are not captured here. The overall freshness of the data is good, with all pollutants updated within the past week, but the uneven number of records per pollutant (for example, five recent rows for PM₁₀ versus a single row for PM₁) means some metrics are based on far fewer observations than others. Users should keep in mind that these snapshots represent specific moments at particular sites rather than a continuous city‑wide picture.

Data notes

The dataset for Melilla includes 29 valid measurements and is marked as Updated within 3 days, with the most recent data recorded on 2026‑02‑10T16:00:00+00:00. These values represent a snapshot of conditions at the time of collection; air quality can differ across neighborhoods and change throughout the day, so this information may not reflect current or localized levels elsewhere in the city.
