Inside the chain directory cclm-sp/chain, you will find a number of files and directories:
Directory for archived simulation output.
Directory where you run a downscaling simulation with GCM data as forcing.
Directory where you run a nested simulation with CCLM data as forcing.
Directory where data for input and output of the chain scripts are temporally stored.
Directory where you find the log files of your simulation, joboutputs, restart files and simulation output of the post-processing job.
