Klimatická změna či emise prekursorů - co bude hrát rozhodující roli v budoucích imisních koncentracích přízemního ozonu?

Tremaskina, Anastasiia

This thesis examines the reasons for potential future outcomes as well as the evolution of future ground-level O3 concentrations. Ground-level O3 is primarily formed by the reaction of precursor emissions, such as nitrogen oxides (NOx) and volatile organic compounds (VOCs), in the presence of solar radiation and warm temperatures. Transport, industrial operations, and energy production are the primary human activities that produce these emissions. Climate change, on the other hand, also has an impact on ground-level O3 concentrations by modifying the atmospheric conditions that promote O3 generation. The frequency and length of high O3 occurrences, for instance, may increase with increasing temperatures and changes in atmospheric circulation patterns, but drought conditions may decrease plant ability to absorb O3 and other pollutants. Additionally, precursor emissions can potentially be impacted by climate change. For instance, rising temperatures may cause plants to produce more biogenic VOCs, and shifting rainfall patterns may have an impact on soil NOx emission rates. Therefore, both precursor emissions and climate change must be considered and addressed in order to correctly anticipate future ground-level O3 concentrations. The work covers the results of previous studies on precursor emissions...
