About the ECCO2 - MITgcm configuration

Here is the MITgcm configuration used: http://mitgcm.org/cgi-bin/viewcvs.cgi/MITgcm_contrib/quarter_degree_global/

The NCEP forcing may be find here: http://ecco2.org/products/model_setups/ncep_rgau/

A summary of the simulations performed may be find here: http://ecco2.org/products/output/latlon/

Then, the available outputs are here: http://ecco2.org/products/output/latlon/output.html

Particularly, 6 hourly and monthly averages list are here: http://ecco2.org/products/output/latlon/exp_lle_nb.txt

Binaries available at MIT

lat-lon grid 1/8 deg simulation

Here is a recap of which outputs are available locally at MIT as binary files for the configuration:
2000-2005 integration,
1/8-deg horizontal grid spacing,
50 vertical levels,
forced by NCEP reanalysis-1 surface atmospheric state and bulk formulae,
surface relaxation to montly Levitus SSS with a relaxation time constant of 44.5 days,
with full dynamic thermodynamic sea-ice model,

Keep in mind that this list is not exhaustive, I only considered what was involved in my Postdoc project.
