Model Name : GEOS-Chem

• Describe the modeling activities of your group (what meteorological, chemical transport and/or radiative transfer models are you using)

Our group uses a 3-D global chemical transport model, GEOS-Chem, which was developed at Harvard University. The model uses Goddard Earth Observing System (GEOS) assimilated meteorological data from the NASA GMAO office. This model also has a nested simulation capability which can be used to focus a region of interest with much finer resolutions. The GEOS-Chem nested simulations use GEOS-Chem global model results as boundary conditions so chemical and meteorological consistency can be obtained. The details on GEOS-Chem can be found on the web (http://acmg.seas.harvard.edu/geos/index.html).

• What emissions inventories are you using.

Anthropogenic and biofuel emissions for Asia region are used Streets 2006 inventory in the model. Biomass burning and biogenic emissions are from GFED2 emission inventory and MEGAN emission inventory, respectively.
