Yes If above answer is no, provide end year model development Code development status When did you indicate the 'code development status'? Model availability As code Source code availability (Or provide future intension) Through owner"Through owner" is not in the list (Through web repository, Through CSDMS repository) of allowed values for the "Source code availability" property.

Yes If above answer is yes IDL Other visualization software 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 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. Testing Describe available calibration data sets -- Upload calibration data sets if available: Describe available test data sets -- Upload test data sets if available: Describe ideal data for testing -- Other Do you have current or future plans for collaborating with other researchers? I am collaborating with Jim Friedson and Bob West at JPL and Erika Barth at SWRI, as well as my adviser, Brian Toon. Is there a manual available? Yes Upload manual if available: Model website if any http://www.ccsm.ucar.edu/models/atm-cam/ Model forum / discussion board Comments CAM-CARMA Introduction History Papers CAM-CARMA Questionnaire Contact Information Model: CAM-CARMA Contact person: Erik Larson (Model developer) Institute: LASP/University of Colorado City: Boulder Country: USA Email: larsonej@colorado.edu 2nd person involved: -- 3rd person involved: -- 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.
