These include surface data, initialization files as well as the namalist file for the model timeloop execution.

Before running the CoLM timeloop program, a namelist being created, this namelist is used to direct the CoLM history output. At sometimes, especially with high resolution running case, lots of output data is produced by the model, and most variables in history data are useless, the is used to handle this situation, we could use it to filter some useless variables, each variable headed with a “+” sign will be exported as normal, each variable headed with a “” sign will be dropped. But when using the graph scripts in graph/ directory, users should modify them to port with the .Also a nam
