In this chapter we describe how to run some special cases that take more than one step to do. The straightforward cases have compsets and/or build-namelist use-cases setup for them or require simple editing of a single-case. All of the cases here require you to do at least two simulations with different configurations, or require more complex editing of the case (changing the streams files).
The five cases we will describe are:
Spinning up the Satellite Phenology Model (CLMSP spinup)
Spinning up the biogeochemistry Carbon-Nitrogen Model (CN spinup)
Spinning up the Carbon-Nitrogen Dynamic Global Vegetation Model (CNDV spinup)
Doing perturbation error growth tests
Running stand-alone CLM with transient historical CO2 concentration
| Caution |
The cases in this chapter are more sophisticated and require more technical knowledge and skill than cases in previous chapters. The user should be very familiar with doing simple cases before moving onto the cases described here. |
To spin-up the CLMSP model you merely need to run CLMSP for 50 simulation years starting from arbitrary initial conditions. You then use the final restart file for initial conditions in other simulations. Because, this is a straight forward operation we will NOT give the details on how to do that here, but leave it as an exercise for the reader. See the Example 4-3 as an example of doing this as the last step for CLMCN.
