The following namelist generates a branch run starting from restart files generated by Example 1. The user may branch a run with the same executable used in the initial run (i.e., without recompiling the code) unless branching is used to test changes in the code (for debugging or sensitivity purposes).

See Example 1 for explanations of namelist variables which remain
unchanged.
NSREST = 3
Requests a branch run.
NELAPSE = -1
Specifies the run's ending time to be one day after the
point of branching.
NREVSN = 'test.clm2.r.1998-01-01-00000'
Supplies the name of the restart file which will initialize this run.
(Note this file can be produced by running example 1 above).
HIST_FINCL2 = 'TV:I'
Add an auxiliary history file with the field ``TV'' that is output instantaneously.
HIST_NHTFRQ = -3,5
Changes the frequency of primary history history writes to every 3
hours. The write frequency of the auxiliary file is every 5 time
steps. This is an example of a change which a user may wish to test
in a branch run.
HIST_MFILT = 2,3
The primary history file will have 2 time samples on every tape. The
auxiliary history file will have 3 time samples on every tape.
