 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.lsr data.seaice  
   mitgcmuv_1 >&! output.txt  
   mkdir exp1  
   mv *tave.0000000010.data exp1  
72    
73  Use matlab script lookat_exp1.m to compare the output  Use matlab script lookat_exp1.m to compare the output
74  of exp1 with that from release1_p16 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 ADI solver.  The solution is  
 compared to that of experiment 1, which used the LSR solver.  
   
 To run Experiment 2:  
   cd ../../../verification/lab_sea/input  
   ln -sf DATA.10hours data  
   ln -sf DATA.SEAICE.adi 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  
   
 Both solvers should and do converge to solutions  
 that are constant at each latitude.  But note that  
 the two solutions are not exactly the same because  
 the two solvers represent slightly different  
 approximations of the viscous/plastic equations.  
   
   
 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.lsr 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  
   
 The accuracy of the dynamic solvers is increased by  
 reducing parameter LSR_ERROR for the LSR solver and  
 by increasing parameter NPSEUDO for the ADI solver.  
 The computational cost/accuracy trade-off is quite  
 high for the ADI solver but relatively small for  
 the LSR solver, which is the default solver.  
   
   
 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.lsr      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  
   
 The comparison here is just for fun.  
 The configuration is too coarse and artificial  
 to reproduce realistic sea-ice conditions.  
   
   
 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.  
   
 To run Experiment 6:  
   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  
   
 Use the matlab script lookat_exp6.m to compare  
 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).  
 2-CPU executable from experiment 4 is required.  
   
 To run Experiment 7:  
   cd ../../../verification/lab_sea/input  
   ln -sf DATA.10hours data  
   ln -sf DATA.SEAICE.nodynamics data.seaice  
   mpirun -np 2 mitgcmuv_2x1  
   mkdir exp7  
   mv *tave.0000000010.data exp7  
   
 Use the matlab script lookat_exp7.m to compare  
 the output of exp7 to that of exp6:  
   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  
   ln -sf DATA.10hours_exf data  
   ln -sf DATA.SEAICE.exf data.seaice  
   mitgcmuv_exf_forcing >&! output.txt  
   mkdir exp8  
   mv *tave.0000000010.data exp8  
   
 Use matlab script lookat_exp8.m to compare  
 the output of exp8 to that of exp1:  
   cd ../../../verification/lab_sea/matlab  
   matlab  
   lookat_exp8  
   
   
 Instructions for running Experiment 9  
 =====================================  
   
 This is a 1-cpu, 10-hour integration used to test CPP option  
 SEAICE_EXTERNAL_FLUXES.  Both the atmospheric state and the  
 open-water surface fluxes are provided by pkg/exf.  
   
 To run Experiment 9:  
   cd ../../../verification/lab_sea/input
