6 c o Header for the use of the Tangent Linear and Adjoint Model
7 c Compiler (TAMC).

10 c
11 c changed: Patrick Heimbach heimbach@mit.edu 06-Jun-2000
12 c - New parameter nlevchk_0 for dimensionalising
13 c common blocks in the undef ALLOW_TAMC_CHECKPOINTING case
14 c - nhreads_chkpt was declared at the wrong place

22 c TAMC checkpointing parameters:
23 c ==============================
24 c
25 c The checkpointing parameters have to be consistent with other model
26 c parameters and variables. This has to be checked before the model is
27 c run.
28 c
29 c nyears_chkpt - Number of calendar years affected by the assimilation
30 c experiment; nyears_chkpt has to be at least equal to
31 c the result of cal_IntYears(mythid).
32 c nmonths_chkpt - Number of months per year; nmonth_chkpt has to be at
33 c least equal to nmonthyear.
34 c ndays_chkpt - Number of days per month; nday_chkpt has to be at least
35 c equal to nmaxdaymonth.
36 c nsteps_chkpt - Number of steps per day; nsteps_chkpt has to be at
37 c least equal to cal_nStepDay(mythid)
38 c ncheck_chkpt - Number of innermost checkpoints.
39 c
40 c ngeom_chkpt - Geometry factor.
41 c nthreads_chkpt - Number of threads to be used; nth_chkpt .eq. nTx*nTy

79 c TAMC keys:
80 c ==========
81 c
82 c The keys are used for storing and reading data of the reference
83 c trajectory.
84 c
85 c The convention used here is:
86 c ikey_<name>
87 c
88 c which means that this key is used in routine <name> for reading
89 c and writing data.
