Monitoring Extreme Meteorological and Pollution Events in Prague: A Station Data Based Analysis

Original language description

In the current climatic scenarios, the European continent faces numerous extremeevents related to both meteorology and pollution. This study analyses the manifestation ofthese events in Prague by utilizing data from various monitoring stations within the capitalcity. Specifically, we examined two recent significant extreme occurrences: a high-temperature anomalous condition during midwinter (January 2023) and the impact of a wildfire inČeské Švýcarsko National Park (July 2022) on the particulate matter (PM) concentrations inPrague. After a brief analysis of the synoptic environment for both cases using reanalysis, anassessment of temperature, wind speed and humidity data are conducted focusing on variousparts of Prague. For the wildfire analysis, we assess PM10 concentration from stations insidePrague, aiming to assess pollution levels. A special focus of this study is to evaluate meteorological and pollution measurements located in Troja Campus, which belongs to the Department of Atmospheric Physics from the Faculty of Mathematics and Physics. While considering all stations in Prague, an average temperature of + 4.1oC is observed in January 2023 andall stations captured the peak occurred on the 1st of January 2023. Regarding the wildfire episode, which occurred in České Švýcarsko in late evening of 23rd July, an impact of highPM10 concentrations in Prague was observed on 26th and 27th July, which was attributed tothe observed strong westerly and northerly winds capable of transporting the pollution towards Prague. Overall, both episodes were effectively captured by the Troja Campus instruments and the data analysed showed consistency between the Troja Campus stations and theCHMI station network regarding the atmospheric variables (for the warm episode) and thediurnal variation with a small difference in observed means (for the pollution episode) highlighting the capability of our monitoring stations to provide data for further studies.
