The top-level JMC Code L Baseline directory contains atm, ocn, and cpl subdirectories along with scripts and files required to build ( build.sh ), execute in batch ( run.sh, tj, tj-driver ) and validate (STDOUT.0000.ref) the baseline code. The file README, also at the top-level, contains details of the contents of each of these directories, files and scripts as well as pointers to the MITgcm release1 documentation (http://mitgcm.org/sealion).
