Air at the AQMS Peje station

Peć, Kosovo

Network: Kosova Environmental Protection Agency ( KEPA) · Station code: XK0005A

In 2025

at least

16 days

with an 8-hour average of ozone (O₃) above the target value of 120 µg/m³.

Readings are missing for part of the period, so the real number may be higher.

Worst day: August 13, 2025, O₃ 136 µg/m³ as a daily average, 1.1 times the limit.

Daily average for 249 of 365 days · data for 2025 not yet finally verified · Yardstick: EU limits (Directive 2008/50/EC)

All figures by year and month

No data has arrived from this station since November 27, 2025 at 20:00

No reading for 314 days.

We take the readings from the European Environment Agency (EEA), and no new values for this station are coming from there. The cause may lie with the station itself or with the data transmission.

Last reading: November 27, 2025 at 20:00

The monitoring networks have not yet finally verified this year’s data. The EEA publishes verified values once a year.

≥ means at least: more than a tenth of the days or hours are missing, so the real number may be higher.

¹ Fewer than 90 % of the hours were measured, so we do not compare this average with the limit.

² Too few readings to compare with the number allowed: the figure covers only what was measured.

■ and a figure in red: more than is allowed for the whole year.

Calculated from the hourly values the EEA publishes. If late values arrive afterwards, an outage gets shorter or disappears.

Where the data comes from

Measured by Kosova Environmental Protection Agency ( KEPA). We take the values from the European Environment Agency (EEA) under the CC BY 4.0 licence.

Values marked provisional have not been fully checked by the network yet. The EEA publishes verified data for the previous year once a year, usually by the end of September.

An hourly value is the average of one hour. We show the end of the hour: the value to 18:00 was measured from 17:00 to 18:00.

A day runs from midnight to midnight local time.

We only show an average when at least three out of four hours in the period have a reading. The EU air quality directive requires this for daily averages, and we apply the same rule to longer periods. We compare an annual average with the EU limit only once 90 % of hours are measured, as the directive requires. For 12 months and for a year we ask for more: if less than 90 % of hours are measured, every full calendar month needs readings for at least half of its hours. Otherwise a whole season could be missing from the average, such as summer, when ozone is highest.

We do not call a difference of up to 10 % a change, nor one of up to 1 µg/m³ at low levels, because weather and measurement uncertainty alone cause differences that size.

When a station sends no reading, the EEA sometimes fills the hour with a model estimate. We draw those hours dashed and leave them out of every average.

The EU limits come from Directive 2008/50/EC. Here they serve as a yardstick for comparison. When more than a tenth of the days or hours are missing, the number of exceedances can only be higher, so we write “at least” in front of it.
