A not-so-clean Clean Monday was yesterday, since the atmospheric circulation favored the transfer of significant amounts of African dust to our country.

Indicatively, according to the meteo of the National Observatory of Athens, the concentration of dust particles with a diameter of less than 10 micrometers (pm10) in Methoni in Laconia during Clean Monday, just before noon, reached 345.5 μg/m3 (micrograms per cubic air meter).

Values ​​greater than 50 µg/m3 are associated with poor air quality, while according to European Union guidelines the average daily value should not exceed 50 µg/m3 more than 35 times during the year.

Dust concentrations in the atmosphere will remain elevated today as well. According to the latest prognostic data of the National Observatory of Athens/meteo.gr, rains will occur in Thrace, Macedonia, Thessaly, Eastern Sterea and Peloponnese as well as in the northern parts of Epirus and Ionia.

Increased atmospheric dust concentrations will result in mud showers in many of the above areas.
