Model Description
Model type: | Modular model for the terrestrial. |
Description: | I am developing a recent adaptation of CAM 3.0 that has been converted to Titan by Friedson et al. at JPL. I am adding the aerosol microphysics from CARMA. |
Technical information
Supported platforms: | Mac OSX |
Programming language: | Fortran77, Fortran90 |
Model development started at: | Model development still takes place. |
To what degree will the model become available: | Source code will be available |
Current license type: | -- |
Memory requirements: | Large |
Typical run time: | varies greatly |
Input / Output description
Input parameters: | -- |
Input format: | ASCII |
Output parameters: | -- |
Output format: | Netcdf files |
Post-processing software (if needed): | No |
Visualization software (if needed): | Yes, IDL |
Process description
Processes represented by 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. |
Key physical parameters & equations: | -- |
Length scale & resolution constraints: | Currently there are only initial data sets for 10x15 degrees longitude and latitude. This model is meant for global scale dynamics. |
Time scale & resolution constraints: | I am running the model with dynamical time steps of 1800 seconds, but it only computes the radiative transfer every 200 timesteps. |
Numerical limitations and issues : | This is a large model that takes significant computing resources to spin up run. |
Testing
Available calibration data sets: | -- |
Available test data sets: | -- |
Ideal data for testing: | -- |
User groups
Currently or plans for collaborating with: | I am collaborating with Jim Friedson and Bob West at JPL and Erika Barth at SWRI, as well as my adviser, Brian Toon. |
