4.1 Subdir: PREP
This subdirectory contains the preparation and preprocessing files for a model
application. It consists of the two subdirectories
REAL_CLM_FILES and SUBS and several ASCII files:
- AN_ID.h
- File contains a list of names of test cases with
the #define statement. The test case to be used
for the model simulation is the only one not
commented out.
- Def_prep.h
- File containing list of initialization features
to be selected, such as LEVITUS,
PARTIAL_CELLS, etc.
- Diecast.h
- File contains parameter statements for array
dimensions and the dimensioning of arrays.
- Makefile
- File contains the makefile commands to compile
and link the preparation files to generate the
executable file prep.
- prep.F
- Fortran code for preprocessing the CANDIE
model.
- Prep_parm.tag_root
- File containing initialization
information for prep.F for the case to be set up. This file
is not not read if the SPECIAL_TEST option is used.
The name tag_root
is the same name supplied to prep.F at execution time to
identify the model initialization.
- /PREP/REAL_CLM_FILES
- This subdirectory contains files to
fill in climatic data sets.
- /PREP/REAL_CLM_FILES/
- AN_ID.h
File contains
the name of the test case being run, as in
the file PREP/ AN\_ID.h.
- /PREP/REAL_CLM_FILES/ fill_dd.F
- Fills original data set. This
routine modified from D.Dietrich, and uses only the TK array.
This routine only fill levels where there is data.
- /PREP/REAL_CLM_FILES/ prep.real_clm.F
- This version differs from v1 in that it uses
DD's poisson smoother
to fill holes in the original (Levitus) T and S files.
This is an abbreviated version used to output
monthly wind stress
and surface T,S on the model grid.
Run it only when needed -- IT IS NOT PREP.F!!
This version outputs a North sponge layer that
is 20 grid cells
wide. The South sponge layer is still 10 cells wide
- /PREP/SUBS
- This subdirectory contains files with the code for
the initialization of various test cases. The
appropriate files are included in prep.F with
preprocessor #include statements.
- /PREP/SUBS/ dgyr_test_case.h
- /PREP/SUBS/ dhem_test_case.h
- /PREP/SUBS/ gsl_tide.h
- /PREP/SUBS/ hb_test_case.h
- /PREP/SUBS/ Hcdf.h
- File contains code to
extract regional subset of etopo5 bathy-metry from a remote file that is
in netcdf format. User specified lat/long window and resolution
WESTDEG is western most longitude degrees (west cell face of I=2 zone)
longitude coordinate increases eastward: 0 < WESTDEG < 360.
For a given grid(long,lat) compute the bracketing
etopo5 lon/lats and get the etopo5 values.
NOTES: (1) assumes knowledge of file structure;
(2) wants longitude (0...360)E, lat=(-90,...90);
(3) does not check for (long,lat) out of range;
(4) uses two subroutines which are at bottom of file.
- /PREP/SUBS/ iw_test_case.h
- /PREP/SUBS/ of_test_case.h
- /PREP/SUBS/ pg_test_case.h
- /PREP/SUBS/ Sfce_flux.h
- File contains code to
read COADS
data for surface heat flux from a netcdf file, and interpolate
it to the model grid.
- /PREP/SUBS/ STRcdf.h
- File contains code to
read Hellerman
and Rosenstein wind
stress data from a netcdf file and interpolate it to the model grid.
- /PREP/SUBS/ TScdf.h
- File contains code to
read the Levitus
T and S data from a netcdf file and interpolate to the model grid.
The code then uses a Poisson equation to get smooth
fields over land, in order to avoid any mismatches between Levitus
and ETOPO5 datasets for land boundaries. The T and S data are
then interpolated to the model grid.
