Yes, I plan on collaborating with others in particular when it comes time to rework the model chemistry modules. +
Haze microphysics can be checked against Bardeen 2008 for initial accuracy. +
I have numerous data sets produced by an 8 processor Mac and a local unix cluster to confirm the model is initialized correctly. +

Dynamics, chemistry, RT, microphysical, and slab ocean model are all coupled, thus the model runs slowly. +

General circulation model of early Earth. Particular detail is paid to chemistry, RT, and haze microphysics +
The model takes about 4-6 model years to reach equilibrium. The modeled time period is from the Archean Earth (3.8 - 2.5 Ga) +
I am developing a GCM based on NCAR's WACC … I am developing a GCM based on NCAR's WACCM model to studied the climate of the ancient Earth. WACCM has been linked with a microphysical model (CARMA). Some important issues to be examined are the climate of the ancient Earth in light of the faint young Sun, reducing chemistry of the early atmosphere, and the production and radiative forcing of Titan-like photochemical hazes that likely enshrouded the Earth at this time. likely enshrouded the Earth at this time. +
