+Instructions for 10-year 1979-1988 arctic40km adjoint, on 15 procs
+last modified by D. Menemenlis (menemenlis@jpl.nasa.gov) on 07/03/06
+--------------------------------------------------------------------
+o cost terms are 
+  * theta/salt climatology (incl. annual cycle)
+  * SST, SSS
+  * daily seaice concentration
+  (see code_ad/ECCO_CPPOPTIONS.h, 
+  input_ad/data.ecco, input_ad/data.seaice)
+o forward part has all kpp, gmredi, seaice,
+  adjoint part has SEAICEuseDYNAMICS=.FALSE., see
+  code_ad/autodiff_inadmode_set_ad.F
+  code_ad/autodiff_inadmode_unset_ad.F
+
+To get code:
+------------
+cvs co -r MITgcm_code
+cd MITgcm
+cvs co -d arctic40km MITgcm_contrib/arctic40km
+cd arctic40km/input_ad
+wget -nd -r -A"*.bin" http://channel.mit.edu/datasets/MITgcm_input_files/MITgcm_contrib/arctic40km/input
+wget -nd -r -A"topog.bin_130_102" http://channel.mit.edu/datasets/MITgcm_input_files/MITgcm_contrib/arctic40km/input
+wget -nd -r -A"*.phc_130_102_25_12" http://channel.mit.edu/datasets/MITgcm_input_files/MITgcm_contrib/arctic40km/input
+cd ../..
+
+Also need to have "ncep_rgau" directory available at same level as MITgcm
+ncep_rgau files are available at http://ecco2.org/products/model_setups/ncep_rgau
+-------------------------------------------------------------------------
+
+To build code (on columbia):
+---------------------------
+mkdir bin
+cd bin
+\rm *
+../tools/genmake2 -of ../tools/build_options/linux_ia64_ifort+mpi_altix_nas -mods ../arctic40km/code_ad
+make depend
+make adtaf
+make -j adall
+
+To run the code:
+---------------
+cd ..
+\cp arctic40km/input_ad/runarctic.csh .
+qsub runarctic.csh
