Seminar: Dr. Athanasios Nenes

*********************************
There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Research Interests:

  • Modeling of aerosol-cloud-climate interactions on a global scale
  • Modeling and parameterization of cloud microphysical processes
  • Thermodynamic modeling of tropospheric aerosols
  • Instrumentation and techniques for characterizing organic-water interactions, hygroscopicitiy and CCN activity of aerosols
  • Laboratory and field studies on CCN activity and aerosol-cloud interactions
  • New particle formation and its impact on CCN concentrations
  • Effect of pollution on marine ecosystem productivity and carbon cycle
  • Impact of marine ecosystem productivity on clouds

 

"Ocean & Climate: Atmospheric Acidity and Impact on Nutrient Deposit"

 

In preparation for the seminar, the students are asked to review the following papers:
