Short Bio

My research addresses the treatment and understanding of aerosol and cloud microphysics in the global aerosol-climate model system. I have been involved in developing a new version of the global aerosol-climate model ECHAM5-HAM of the Max Planck Institute for Meteorology. Together with my colleagues in Europe, I use ECHAM5-HAM2 to estimate the climate effect of anthropogenic aerosols and quantify the uncertainty due to using different physical parametrizations and model configurations such as resolution, with and without nudging, and the coupling between competing processes.
 
In spring 2011, I moved to Pacific Northwest National Lab in Richland, WA, USA. My current research focuses on using aircraft and satellite measurements to constrain ice cloud formation parametrization in global climate models.

Research Interests

  • Global aerosol modeling 
  • Aerosol and cloud microphysics
  • Aerosol effect on cold clouds
  • Long-range tracer transport and its inter-annual variability
  • Radon - Low-tropospheric Ionization - Aerosol Nucleation 

Radon Data

A global radon emission flux map has been created using the most recent regional radon flux maps available. The map has been reported in Zhang et al. (2011). Please contact me if you are interested in using it.
