Guidelines

Studium tvorby sekundárního organického aerosolu (SOA) z primárních prekurzorů - chemické transformace vedoucí ke snížení volatility SOA. Seznámení se modelováním troposférické chemie pomocí chemicko-transportních modelů. Studium modelových konceptů popis tvorby jak inorganického sekundárního aerosolu (secondary inorganic aerosol - SIA), tak a zejména sekundárního organického aerosolu, studium nejistot v modelovém popisu, analýza vlivu emisí různých prekurzorů a zdrojů na tvorbu SOA. Aktivní srovnávání modelovaných dat se staničními měřeními, implementace satelitních pozorování o optické tloušťce aerosolů a srovnání s modelem. Studium tvorby aerosolů v městském prostředí a vyhodnocení vlivu městských meteorologických efektů (např. interakce s městským tepelným ostrovem).

Preliminary scope of work in English

The numerical model representation of the formation of secondary aerosol are burdened with still high uncertainty, especially in case of the secondary organic aerosol with complicated nucleation pathways from low-volatile precursors. The phd project focuses on the model representation of formation of organic aerosol from gas-phase precursors and analyze the sensitivity of their concentrations on emission from different sectors and regions, on meteorological conditions as well as on different model parameterization of their formation from primary precursors. Extensive comparison of model data to observations will be a crucial part of the topic.
Outcome of a successful research will be a comprehensive assessment of the sources of secondary organic aerosol for the region of Central Europe.
