1 Example: Labrador Sea Region with Sea-Ice
2 =========================================
3
4 This example sets up a small (20x16x23) Labrador Sea experiment
5 coupled to a dynamic thermodynamic sea-ice model.
6 A brief description of the sea-ice model is in "seaice.ps".
7
8 The domain of integration spans 280E to 320E and 46N to 78N.
9 Horizontal grid spacing is 2 degrees.
10 The 23 vertical levels and the bathymetry file
11 bathyFile = 'bathy.labsea'
12 are obtained from the the 2-degree ECCO configuration.
13
14 Integration is initialized from annual-mean Levitus climatology
15 hydrogThetaFile = 'LevCli_temp.labsea'
16 hydrogSaltFile = 'LevCli_salt.labsea'
17
18 Surface salinity relaxation is to the monthly mean Levitus climatology
19 saltClimFile = 'SSS.labsea'
20
21 Forcing files are a 1979-1999 monthly climatology computed from the
22 NCEP reanalysis (see pkg/seaice/SEAICE_FFIELDS.h for units and signs)
23 uwindFile = 'u10m.labsea79' # 10-m zonal wind
24 vwindFile = 'v10m.labsea79' # 10-m meridional wind
25 atempFile = 'tair.labsea1979' # 2-m air temperature
26 aqhFile = 'qa.labsea1979' # 2-m specific humidity
27 lwdownFile = 'flo.labsea1979' # downward longwave radiation
28 swdownFile = 'fsh.labsea1979' # downward shortwave radiation
29 precipFile = 'prate.labsea1979' # precipitation
30
31 The experiment uses pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf.
32 The test is a 1-cpu, 10-hour integration. Both the atmospheric
33 state and the open-water surface fluxes are provided by pkg/exf.
34
35 More pkg/seaice test experiments, configured for low and
36 high-resolution global cube-sphere domains are described
37 in MITgcm_contrib/high_res_cube/README_ice.

40 Using testscript to test sea-ice code
41 =====================================
42
43 Running the testscript experiment:
44 cd MITgcm/verification
45 ./testreport -t lab_sea
46
47 Note that fairly large differences in accuracy occur across different
48 platforms. For example, testscript comparisons between g77 (Linux)
49 and f77 (SGI) generated output gives:

51 T S U V
52 C D M c m s m s m s m s
53 n p a R g m m e . m m e . m m e . m m e .
54 f n k u 2 i a a d i a a d i a a d i a a d
55 g d e n d n x n . n x n . n x n . n x n .

60 Instructions for generating and running a 1-CPU experiment
61 ==========================================================
62
63 cd MITgcm/verification/lab_sea
64 mkdir build
65 cd build
66 cp ../code/*.h ../code/packages.conf .
67 ../../../tools/genmake2
68 make depend
69 make
70 cd ../input
71 ../build/mitgcmuv > output.txt
72
73 Use matlab script lookat_exp1.m to compare the output
74 of exp1 with that from checkpoint51f sea-ice code:
75 cd ../../../verification/lab_sea/matlab
76 matlab
77 lookat_ice
78
79
80 Instructions for generating and running a 2-CPU experiment on kalpana
81 =====================================================================
82
83 cd MITgcm/verification/lab_sea
84 mkdir build
85 cd build
86 \cp ../code/*.h ../code/packages.conf .
87 \cp ../code/SIZE.h_mpi SIZE.h
88 ../../../tools/genmake2 -of ../../../tools/build_options/linux_ia64_efc+mpi_altix
