Influence of model aerosol type on AOD estimation in different heights
Strongest influence near/above PBL height.

Annual cycle strongly varies among species
Summary • First steps towards Bavarian-Slovenian spaced-based pollution monitoring • Model results show that AOD estimation is highly influenced by aerosols in
higher altitudes. Thus, vertical resolution is important to get comparisons right.
• Aerosol composition strongly varies during the year. Composition is important to verify and understand aerosol sources.
