Air at the Desinić station

Desinić, Croatia

Network: Državna mreža za trajno praćenje kvalitete zraka · Station code: HR0012A

This year, up to yesterday (October 6)

53 days

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

The target value allows 25 such days a year, averaged over three years.

5 days

with a daily average of particulate matter PM10 above the EU limit of 50 µg/m³.

35 days are allowed in the whole year.

Worst day: September 5, 2026, O₃ 160 µg/m³ as a daily average, 1.3 times the limit.

How the air is changing

Over the last seven days there was more PM10, PM2.5, O₃, and SO₂ in the air than the week before.

  • PM10: average 16.6 µg/m³, week before 9.9 µg/m³
  • PM2.5: average 11.8 µg/m³, week before 8.8 µg/m³
  • NO₂: average 4.6 µg/m³, week before 4 µg/m³
  • O₃: average 95.7 µg/m³, week before 76.8 µg/m³
  • SO₂: average 13.7 µg/m³, week before 11.2 µg/m³

Last month there was more PM2.5 and less PM10 and O₃ in the air than the month before.

  • PM10: average 7.7 µg/m³, month before 10.5 µg/m³
  • PM2.5: average 6.3 µg/m³, month before 4.6 µg/m³
  • NO₂: average 3.4 µg/m³, month before 3 µg/m³
  • O₃: average 79 µg/m³, month before 106.7 µg/m³

* 2026 up to October 6; the average since the start of the year is not yet an annual average.

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 Državna mreža za trajno praćenje kvalitete zraka. 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.
