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.

 Instructions for running Experiment 1  
 =====================================  
   
 This is a 1-cpu, 10-hour integration used to make sure that all  
 the files are available and that the sea-ice model compiles and  
 runs.  The reading of atmospheric forcing files and the computation  
 of open-water bulk fluxes are carried out within pkg/seaice.  
   
 To run Experiment 1:  
   cd ../../../verification/lab_sea/input  
   ln -sf DATA.10hours data  
   ln -sf DATA.SEAICE.adi data.seaice  
   mitgcmuv_1 >&! output.txt  
   mkdir exp1  
   mv *tave.0000000010.data exp1  
   
 Use matlab script lookat_exp1.m to compare the output  
 of exp1 with that from release1_p10 sea-ice code:  
   cd ../../../verification/lab_sea/matlab  
   matlab  
   lookat_exp1  
   
   
 Instructions for running Experiment 2  
 =====================================  
   
 This is a 1-cpu test of the LSR solver.  The solution is  
 compared to that of experiment 1, which used the ADI solver.  
   
 To run Experiment 2:  
   cd ../../../verification/lab_sea/input  
   ln -sf DATA.10hours data  
   ln -sf DATA.SEAICE.lsr data.seaice  
   mitgcmuv_1 >&! output.txt  
   mkdir exp2  
   mv *tave.0000000010.data exp2  
   
 Use matlab script lookat_exp2.m to compare  
 the output of exp2 to that of exp1:  
   cd ../../../verification/lab_sea/matlab  
   matlab  
   lookat_exp2  
   
   
 Instructions for running Experiment 3  
 =====================================  
   
 This is a test of periodic boundary conditions for LSR  
 and ADI solvers.  The domain has a flat bottom and  
 is periodic both in the x and the y directions.  
 All forcing files are null or constant (u10m = v10m = 5 m/s).  
   
 To run Experiment 3:  
   cd ../../../verification/lab_sea/input  
   ln -sf DATA.1hour data  
   ln -sf DATA.SEAICE.testadi data.seaice  
   mitgcmuv_1 >&! output.txt  
   mkdir exp3a  
   mv *tave.0000000001.data exp3a  
   ln -sf DATA.SEAICE.testlsr data.seaice  
   mitgcmuv_1 >&! output.txt  
   mkdir exp3b  
   mv *tave.0000000001.data exp3b  
   
 Use matlab script lookat_exp3.m to compare  
 the output of exp2 to that of exp1:  
   cd ../../../verification/lab_sea/matlab  
   matlab  
   lookat_exp3  
   
 If the dynamic ice solvers are correct, they should converge to a  
 constant solution.  The tests above show that both the ADI and the LSR  
 solver are unable to handle periodic domains and therefore that they  
 cannot be "correctly" parallelized.  
   
   
 Instructions for running Experiment 4  
 =====================================  
76    
77  This is a 2-cpu, 10-hour integration used to test  There is comparison output in the directory:
78  tile edges for sea-ice dynamic solvers.    results/output.txt
79    
80  To run Experiment 4:  Use matlab script lookat_ice.m to compare the output
81    cd ../../../verification/lab_sea/input   with that from checkpoint51f sea-ice code:
   ln -sf DATA.10hours data  
   ln -sf DATA.SEAICE.adi data.seaice  
   mpirun -np 2 mitgcmuv_2x1  
   mkdir exp4  
   mv *tave.0000000010.data exp4  
   
 Use the matlab script lookat_exp4.m to compare  
 the 2-cpu output to that of exp1:  
82    cd ../../../verification/lab_sea/matlab    cd ../../../verification/lab_sea/matlab
83    matlab    matlab
84    lookat_exp4    lookat_ice
   
 The inaccuracy at the tile boundary can be decreased by increasing  
 NPSEUDO in data.seaice at the expense of computation time.  
 Also as sea-ice ages (thickens) the difference at the tiles becomes  
 increasingly small.  For solver pkg/seaice/adi.F a value of NPSEUDO=10  
 appears adequate for forward integrations but cannot be used for sea-ice  
 adjoint model.  Work is underway to fix this problem.  
   
   
 Instructions for running Experiment 5  
 =====================================  
85    
86  This is a 2-cpu, 2-year, test integration.  It illustrates  Instructions for generating and running a 2-CPU experiment
87  convention used by seaice_get_forcing.F for multi-year forcing.  ==========================================================
   
 To run Experiment 5:  
   cd ../../../verification/lab_sea/input  
   ln -sf      DATA.2years             data  
   ln -sf  DATA.SEAICE.adi      data.seaice  
   ln -sf  evap.labsea1979  evap.labsea1980    
   ln -sf   flo.labsea1979   flo.labsea1980    
   ln -sf   fsh.labsea1979   fsh.labsea1980    
   ln -sf prate.labsea1979 prate.labsea1980  
   ln -sf    qa.labsea1979    qa.labsea1980      
   ln -sf  tair.labsea1979  tair.labsea1980    
   ln -sf    u10m.labsea79    u10m.labsea80      
   ln -sf    v10m.labsea79    v10m.labsea80      
   mpirun -np 2 mitgcmuv_2x1  
   
 Use the matlab script lookat_exp5.m to compare  
 the 2-cpu output to SMMR-SSM/I data:  
   cd ../../../verification/lab_sea/matlab  
   matlab  
   lookat_exp5  
88    
89  Disclaimer:    cd MITgcm/verification/lab_sea
 The comparison here is just for fun, not really supposed  
 to look anything like the data.  
 Otherwise it would put a lot of people out of business :-)

92  =====================================    cd build
93      ../../../tools/genmake2 -mpi -mods ../code [-of my_platform_optionFile]

   mkdir exp6  
   mv *tave.0000000010.data exp6

 the output of exp6 to that of exp1:  
   cd ../verification/lab_sea/matlab  
   matlab  
   lookat_exp6  
   
 Instructions for running Experiment 7  
 =====================================  
   
 This is a 2-cpu, 10-hour integration used to test  
 tile edges for sea-ice thermodynamics (no dynamics).

 verification/testscript.  It is a 1-cpu, 10-hour integration  
 used to test CPP option SEAICE_EXTERNAL_FORCING.  Atmospheric  
 state is read-in using pkg/exf, rather than pkg/seaice routines.

 =====================================  
   
 This is a 1-cpu, 10-hour integration used to test CPP option  
 SEAICE_EXTERNAL_FLUXES.  Both the atmospheric state and the
