Air quality today

The air quality in Kallithea Municipal Unit is classified as Good today. The primary pollutant measured is PM10, with six valid observations recorded. The reference value for PM10 is 10.0 µg/m³, and the current data are shown via OpenAQ.

Measurements indicate that PM10 levels are within the referenced limit, confirming the Good classification based on the available readings. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Kallithea Municipal Unit contains measurements of four pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO₂), ozone (O₃) and particulate matter up to 10 µm (PM₁₀). The information comes from a total of eleven recorded rows, which are drawn from two monitoring stations in the area. For three of the pollutants (NO₂, O₃ and PM₁₀) the most recent values were uploaded on 2026‑02‑10 at 20:00 UTC, meaning that the latest data for these substances is less than three days old. In contrast, the NO reading dates back to 2024‑03‑11 at 12:00 UTC and is flagged as “old data”, so the nitrogen monoxide information is considerably less current than the other three.

Looking at the numbers, NO₂ values range from a low of 1.0 µg/m³ to a high of 9.0 µg/m³, with a median of 5.0 µg/m³ and most observations falling between roughly 2 µg/m³ (10th percentile) and 8 µg/m³ (90th percentile). Ozone shows a tighter spread: the minimum recorded level is 55.0 µg/m³, the maximum 75.0 µg/m³, with a median of 74.0 µg/m³ and the central 80 % of data lying between about 59 µg/m³ and 75 µg/m³. PM₁₀ concentrations are modest, varying from 7.0 to 15.0 µg/m³; the median sits at 10.0 µg/m³ and most readings cluster between roughly 8 µg/m³ and 14 µg/m³. The NO measurement is a single constant value of 1.0 µg/m³, reflecting only one recent entry for that pollutant.

Overall the dataset provides fairly fresh coverage for three key pollutants across two stations, but the nitrogen monoxide data is outdated and limited to a single point. Because the observations come from just two locations, conditions in other parts of Kallithea may differ from what these rows capture, especially at times when measurements are not being updated regularly.

Data notes

The data shown for Kallithea Municipal Unit is based on six valid measurements and was refreshed within the past three days, with the latest update recorded at 2026‑02‑10T20:00:00+00:00. This snapshot reflects conditions at a specific time and place; air quality can differ across neighborhoods and vary throughout the day, so values may not represent every location or moment in the city.
