Often it may take several simulated years to ``spin up'' the model. For example, in CCSM mode it may take numerous decades to spin up the deep soil liquid water. As a result, it has become necessary to provide users with the tool to create a new initial dataset using a spun up initial dataset at another resolution or landmask. In CLM3.0 we are providing such a tool, interpinic, in the directory tools/interpinic. The only constraint is that the user must have already created a ``template'' initial dataset at the new resolution before this tool is used. This can be done by running the model for one day as in Example 1 but with an additional namelist setting:
hist_crtinic = 'DAILY'
A new initial dataset will be created as a result of this run. The tool interpinic will then overwrite the non spun-up values of CLM3.0 variables in this initial dataset with spun-up values from the spun-up initial dataset.
