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 model compiles and integrates.  It  
 is the default experiment of "verification/testscript lab_sea".  
   
 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

74  of exp1 with that from release1_p10 sea-ice code:  of exp1 with that from checkpoint51f 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  
 =====================================  
   
 This is a 2-cpu, 10-hour integration used to test  
 tile edges for sea-ice dynamic solvers.  
   
 To run Experiment 4:  
   cd ../../../verification/lab_sea/input  
   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:  
75    cd ../../../verification/lab_sea/matlab    cd ../../../verification/lab_sea/matlab
76    matlab    matlab
77    lookat_exp4    lookat_ice
78    
 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.

83  Instructions for running Experiment 5    cd MITgcm/verification/lab_sea
84  =====================================    mkdir build
85      cd build
86  This is a 2-cpu, 2-year, test integration.  It illustrates    \cp ../code/*.h ../code/packages.conf .

89  To run Experiment 5:    make depend
90    cd ../../../verification/lab_sea/input    make
91    ln -sf      DATA.2years             data    cd ../input
92    ln -sf  DATA.SEAICE.adi      data.seaice    mpirun -np 2 ../build/mitgcmuv

   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  
   
 Disclaimer:  
 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 :-)

 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).

   matlab  
   lookat_exp7

 This is the default experiment which is executed by  
 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.
