Hi Sir,
Thank you for offering me this opportunity . This will definitly help me.
The link to the experiments (experiments.tar.gz) is here :
http://www.4shared.com/archive/NSDlcGGW/experimentstar.html
To note further :
(a) i am using, MITgcmUV version: checkpoint63c.
(b) The attached experiments are :
exp1d : In "data" file u/v wind stress files are used.
exp1de : In "data.exf: files u/v wind stress files are used.
(c) The input(bathyfile, temperature , salinity and the wind stress files)
to both the experiments are SAME.
I hope i have given the complete setup.
Thank you .
