Air quality today

The air quality today in Rome is classified as USG. The primary pollutant identified is PM2.5, with a measured concentration of 36.16 µg/m³. In addition, the reference value for PM10 stands at 26.0 µg/m³, based on 96 valid measurements collected via OpenAQ.

These figures reflect the current monitoring snapshot for the city. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

Rome’s OpenAQ feed contains data for carbon monoxide (CO), nitrogen oxide (NO), nitrogen dioxide (NO2), combined nitrogen oxides (NOX), ozone (O3), particulate matter of 1 µm, 2.5 µm and 10 µm (PM1, PM2.5, PM10), sulfur dioxide (SO2), temperature, relative humidity and the additional metric UM003. The dataset comprises 114 individual rows collected from 25 monitoring stations across the city.

The most recent measurements are all within the past week. CO, NO2, O3, NO, NOX, PM10 and SO2 were last updated on 2026‑02‑09 03:00 UTC, while PM2.5 was refreshed more recently on 2026‑02‑10 21:00 UTC. The oldest timestamp among the pollutants is for CO at 2026‑02‑09 03:00 UTC, which still falls within a seven‑day freshness window.

Across the pollutants the number of reporting rows varies. NO2 appears in 24 rows with a median value of 12 µg/m³ and an observed range from 2 to 84 µg/m³; O3 is reported in 18 rows, median 66.5 µg/m³, spanning 10‑82 µg/m³. NO and NOX each have 15 rows, showing medians of 2 µg/m³ (range 0‑17) and 26 µg/m³ (range 4‑80) respectively. PM10 is present in 15 rows (median 17 µg/m³, range 13‑31), while PM2.5 has the fewest rows at 12, with a median of 9 µg/m³ and a maximum of about 36 µg/m³ recorded at Via Fanfulla da Lodi. SO2 is reported in only 7 rows, median 2 µg/m³, ranging from –1 to 2.7 µg/m³, and CO appears in just 4 rows, median 550 µg/m³, spanning 300‑700 µg/m³.

These figures show that while most key pollutants have decent spatial coverage, some—particularly SO2, CO and PM2.5—are captured by relatively few stations, which can lead to localized gaps in the picture of air quality. The overall data set is recent, but the uneven number of rows per pollutant means conditions may differ across neighborhoods and times not directly represented in the current sample.

Data notes

The dataset for Rome includes 96 valid measurements and is updated within 3 days, with the most recent data recorded at 2026‑02‑10T21:00:00+00:00. This snapshot reflects conditions across the monitoring network at that time; however, air quality can differ by specific location and moment within the city, so values may not represent every street or neighborhood precisely.
