On-going Hg and POPs Working Group Developments
- Development of GEOS-5 0.5x0.667 nested grid Hg simulation over the N. American domain. (contact: Yanxu Zhang, UW).
- Implement NEI 2005 Hg emission inventory over US. (contact: Yanxu Zhang, UW).
- Option to use GEOS-Chem Br/BrO fields from Justin Parrella. (contact: Yanxu Zhang, UW & Justin Parrella, Harvard).
- Implement improved bromine explosion emission and chemistry in the Arctic (contact: Jenny Fisher, Harvard).
- Implement improved Hg reduction and re-emission in snow (contact: Jenny Fisher, Harvard).
- Implement Hg source to Arctic Ocean from riverine inputs (contact: Jenny Fisher, Harvard).
