Volcanic eruptions are one of the most important sources of natural aerosol. Their negative impacts on air quality (the effects of volcanic exhaust) can be observed via long-range transport to locations far from the eruption. One of the most recent events of volcanic activity was a volcanic eruption on La Palma in the fall of 2021 (Cumbre Vieja Volcano, La Palma Island, Canary Islands, 28°36'54 ,N 17°52'07 ,W, 1,949 m a.s.l.). The impact of the volcanic eruption on air quality, which occurred 3600 km from the National Atmospheric Observatory Košetice, was studied using a combination of ground-based measurements and vertical profile analyzes. Since a new instrument (LIDAR) has extended the equipment of our station, vertical profile analyzes were performed.
