 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  
72

74  of exp1 with that from release1_p10 sea-ice code:  of exp1 with that from checkpoint51f sea-ice code:
75    cd ../../../verification/lab_sea/matlab    cd ../../../verification/lab_sea/matlab
76    matlab    matlab
77    lookat_exp1    lookat_ice
   
   
 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.  
78    
 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 look at  
 results from exp3a and exp3b:  
   cd ../../../verification/lab_sea/matlab  
   matlab  
   lookat_exp3  
   
 If the dynamic ice solvers are correct, they should converge to a  
 solution that is constant at each latitude.  
   
   
 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:  
   cd ../../../verification/lab_sea/matlab  
   matlab  
   lookat_exp4  
79    
80  The inaccuracy at the tile boundary can be decreased by increasing  Instructions for generating and running a 2-CPU experiment on kalpana
81  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.  With NPSEUDO=300 or greater, the tile disappears, but the  
 computational cost is very large (11 times that of teh forward model).  
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

90      make
91      cd ../input
92      mpirun -np 2 ../build/mitgcmuv
93    
 Instructions for running Experiment 5  
 =====================================  
   
 This is a 2-cpu, 2-year, test integration.  It illustrates  
 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  
   
 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 :-)  
   
 Instructions for running Experiment 6  
 =====================================  
   
 This is a 1-cpu test of sea-ice thermodynamics (no dynamics).  
 The solution is compared to that of experiment 1.

   cd ../../../verification/lab_sea/input  
   ln -sf DATA.10hours data  
   ln -sf DATA.SEAICE.nodynamics data.seaice  
   mitgcmuv_1 >&! output.txt  
   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).

   cd ../verification/lab_sea/matlab  
   matlab  
   lookat_exp7  
   
   
 Instructions for running Experiment 8  
 =====================================  
   
 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.  
 This experiment uses pkg/gmredi, pkg/kpp, pkg/seaice, and pkg/exf.  
   
 To run Experiment 8:  
   cd ../../../verification/lab_sea/input
