Using the RadApp tool
The RadApp tool is a lightweight application running thru MAPL_Cap that runs the Radiation gridded component as well as the Pchem gridded component to provide aerosols to the radiation. Since it is run through MAPL_Cap the application can be run for multiple time steps and out any export of the Radiation components through the History as in the full GEOS5 model. The application uses ExtData to drive the tool with external data on disc.
