Air at the Murska Sobota-Rakican station

Murska Sobota, Slovenia

Network: Slovenian Environment Agency · Station code: SI0033A

This year, up to yesterday (October 6)

at least

49 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.

In 2025: 31 days above the limit, the target value allows 25 as a three-year average.

8 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: July 30, 2026, O₃ 158 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, NO₂, and O₃ in the air than the week before.

  • PM10: average 26.7 µg/m³, week before 13.7 µg/m³
  • PM2.5: average 12.1 µg/m³, week before 7.4 µg/m³
  • NO₂: average 12.1 µg/m³, week before 9.7 µg/m³
  • O₃: average 58.9 µg/m³, week before 45.4 µg/m³

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

  • PM10: average 11.7 µg/m³, month before 15.1 µg/m³
  • PM2.5: average 5.2 µg/m³, month before 7.4 µg/m³
  • NO₂: average 9.1 µg/m³, month before 9.2 µg/m³

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 Slovenian Environment Agency. 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.
