Summary of How the Aerosol Modeling Testbed Functions
The general methodology of how aerosol process modules are evaluated within the Aerosol Modeling Testbed is depicted in the diagram below. Scripts have been set up to streamline this process by minimizing tedious and redundant tasks commonly performed by everyone. Consequently, users can focus on science issues instead.
"Check-out" a version of WRF-Chem that has a default treatment A for a specific aerosol process. Add alternative treatments B and C to be tested.
Execute the model using configuration files set up for a testbed case. The output for treatments B and C are saved in an archive that already contains the "control" simulation output using treatment A.
Execute the Analysis Toolkit to access observations, extract model output, compute statistics, create graphics, and archive the results.
Appraise the performance of treatments B and C in relation to treatment A. If desired, the process can be repeated for the same case or other testbed cases.
In this way, incremental changes in the performance are quantified for targeted aerosol processes, while all other atmospheric processes remain the same.
