User's Guide to NCAR CCM0B

Section III describes the data organization of the model, including the data buffer structures and the data flow of the model. Section IV describes a typical model run. It explains the job control language (JCL), datasets local to the job, input control parameters, required initial data, normal output from the model, and the save/restart process for continuing model runs or recovering from abnormal terminations.

Section V explains steps for adding new variables to the model buffers and gives examples of such changes. It also discusses modifications needed to change model resolution. This report, along with a report describing individual subroutines of the model (Williamson et al., 1983), and a report describing the model equations, physical parameterizations, and computational aspects (Williamson, 1983) are intended to provide sufficient documentation to allow users to understand, modify and use the model.
