| Process description model | |
|---|---|
| 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 key physical parameters and equations | -- |
| 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. |
