Creating a new set of NEMO experiment data

This section describes how to create a new set of NEMO input data. This is useful as it allows multiple sets of identical input data to be generated in separate directories which is useful when benchmarking the code. Andrew Coward supplied several scripts in the ORCA/bin directory which set up new experiment directories. They are used as follows:-

1. Edit setup_ex1 to change the experiment number from 001 to the appropriate value, e.g. 002, 003 etc.
2. Execute setup_ex1. This script creates a new directory with the appropriate number (e.g. EXP002) and populates it with symbolic links to the invariant model data. It also copies in the default versions of the namelist control files and several management scripts.
3. Edit linkcore to change the experiment number (e.g. set nex = 002) as used in step 1. Also ensure that the path to the experiment directory is correctly set.
4. Run linkcore. This script creates the symbolic links for to the DFS3 versions of the CORE forcing fields.

With NEMO V3.0 the setup and linkcore scripts were modified so that they take the name (number or characters) that will be pre-pended to the experiment directory name. E.g. the following commands will create a new run directory called EXP_V3.0_001:

./setup_experiment 001
./linkcore_experiment 001
