Nicole Mölders aka Carmen N. Moelders
Since 1988, I have been involved in numerical modeling of the physics and chemistry of the atmosphere. I have used mesoscale models to investigate human and natural (e.g. fire, volcanic eruptions, anthropogenic emissions, land-use changes) impacts on weather, air quality and climate. In close cooperation with hydrologists and geologists I coupled a hydrologic and meteorological model and developed an integrative hydrometeorological model.

My research activities are mainly focused on the theoretical aspects of atmospheric sciences, in particular physics of the planetary boundary layer, atmospheric turbulence and its impact upon atmospheric chemistry, atmospheric dynamics, atmospheric radiation, cloud physics, micro- and mesoscale numerical modeling, and climate change. In some of these fields I have used principles of dimensional analysis successfully.
