Physics and chemistry of the ozone layer and propagation of solar radiation through the atmosphere. Interactions of solar radiation with atmospheric constituents (atmospheric aerosols and atmospheric gases). Radiative transfer modeling and impacts of UV radiation. Solar energy.
Research is carried out in the area of atmospheric remote sensing with the help of laser sources (lidar techniques), focusing mainly on particulates and ozon.
Atmospheric and Environmental Physics with emphasis on Global Change; climate change; greenhouse warming effects on the atmosphere; anthropogenic and natural variability of stratospheric and tropospheric ozone and related effects on Ultra Violet radiation, stratospheric dynamics and climate. Use and development of a fully coupled Chemistry-Climate Model (EMAC- Echam5/Messy) to simulate evolution of the atmosphere in the 21st century.
