Air quality today

The air quality in the Municipality of Korydallos is currently classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 17.61 µg/m³ based on fifteen valid observations reported through OpenAQ.

Data for this assessment are limited to the available measurements and do not include additional pollutants or comparative values. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Korydallos air‑quality dataset currently contains six measured variables – PM1, PM2.5, PM10, relative humidity, temperature and particle count (UM003) – drawn from four sensor rows. Three of the pollutants (PM1, PM2.5, relative humidity, temperature and UM003) have their most recent readings dated 2026‑02‑10 21:00 UTC, meaning they are all updated within the last three days. The fourth variable, PM10, is represented by a single older record from 2025‑01‑13 23:00 UTC, so its information is considerably less current than the rest.

Across the recent rows the observed concentrations span a modest range. PM1 values vary between about 2.9 and 8.7 µg/m³ with a median near 7.2 µg/m³, while PM2.5 ranges from roughly 5.3 to 17.6 µg/m³ and centers around 16 µg/m³. Relative humidity is recorded between 48.9 % and 74.9 %, with a typical value close to 62 %. Temperature measurements cover 10.5 °C to 19.3 °C, medianing near 15 °C. Particle count (UM003) shows counts from about 505 to 722 particles/cm³, median around 624.

The dataset therefore offers fairly fresh data for most pollutants but is limited in spatial coverage – only four rows contribute, and the older PM10 record highlights an uneven temporal distribution across variables. Users should keep in mind that conditions can differ across neighborhoods and over time, especially where the latest measurements are not available.

Data notes

The dataset for the Municipality of Korydallos includes fifteen valid measurements and is updated within three days, with the most recent data recorded on 2026‑02‑10 at 21:00 UTC. This information reflects a snapshot in time; air quality can differ across neighborhoods and change throughout the day, so conditions you experience may not exactly match these values.
