Process
Describe processes represented by the model
|
CAM treats radiative transfer, tidal forcing from Saturn, a planetary boundary layer and surface interaction, thermal conduction in the soil and chemistry. The CARMA part of the code does the aerosol microphysics involving emission, coagulation and sedimentation.

|
Describe length scale and resolution constraints
|
Currently there are only initial data sets for 10x15 degrees longitude and latitude. This model is meant for global scale dynamics.
|
Describe time scale and resolution constraints
|
I am running the model with dynamical time steps of 1800 seconds, but it only computes the radiative transfer every 200 timesteps.
|
Describe any numerical limitations and issues
|
This is a large model that takes significant computing resources to spin up run.
