Lidar Vertical Profile Analyzes at National Atmospheric Observatory Košetice during Volcano Eruption on La Palma Island.

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
