DFS4 Surface Forcing page

This page contains links to the DFS4 surface forcing datasets which have been compiled from NCEP and ECMWF reanalysis products by the Drakkar group. Details will soon be available in "An ERA40-based atmospheric forcing for global ocean circulation models" by Laurent Brodeau, Bernard Barnier, Anne-Marie Treguier, Thierry Penduff and Sergei Gulev, 2009 which has been accepted for publication in Ocean Modelling. The data available here are all on their respective source grids ready for use with the interpolation on the file option. NOCS is only supporting the use of these data with the sbc_core option:

 ln_blk_core = .true. 
The namelist.v3.2 file contains the setting for this option which will require the following weights files:

Forcing data for each of the years 1958 through to 2006 inclusive can be obtained from yearly tar files (e.g. 1958.tar) residing in:
