Example: Subtropical North Atlantic Subduction area

• with KPP & shortwave heating
• no GMRedi

Configure and compile the code:

cd build
../../../tools/genmake2 -mods ../code [-of my_platform_optionFile]
make depend
make
cd ..

To run:

cd run
ln -s ../input/* .
../input/prepare_run
ln -s ../build/mitgcmuv .
./mitgcmuv > output.txt
cd ..

There is comparison output in the directory:

results/output.txt

A FORTRAN program provides a verification procedure. It is based on the boundary layer depth and will either issue: 'North Atlantic test passed. KPPhbl file is unchanged.' or: 'North Atlantic test failed. KPPhbl file has changed.'

cd run
ln -sf ../output/KPPhbl.001.001.data KPPhbl_orig
f77 ../results/comp_orig.F -o comp_orig
comp_orig

N.B.: On ORIGIN 2000 use f77 -bytereclen

A matlab script, matlab/comp_output.m, creates plots for reference (c32) and new surface temperature, boundary layer depth, meridional section of tracer diffusivities, and corresponding differences.

Comments: The input data is real*4.
