| Harvard | Improved atmospheric oxidation mechanism for Hg(0) including updated Dibble chemistry and other updates, constrained and evaluated to match the ensemble of global atmospheric observations. The mechanism will rely on updated GEOS-Chem Br and Cl fields currently being developed by Johan Schmidt in a separate Harvard project focused on reconciling the model with new aircraft and satellite observations of BrO and HOBr. Johan Schmidt's work is expected to be submitted for publication in summer 2015 and at that point his 3-D halogen fields can be submitted for inclusion in the standard GEOS-Chem Hg model. We expect to submit our finalized and evaluated Hg(0)/Hg(II) mechanism for publication in summer/fall 2015 and at that point this will also be submitted to the standard GEOS-Chem model. | Hannah Horowitz Johan Schmidt | 9 Sep 2014 |
