[MITgcm-support] gluemnc and nc file restart

[xiao at cims.nyu.edu]

Hi Jean-Michel,

Thank you for your reply.

In addition, do you/anyone has any idea about why I got error message "no
Y-coordinate found" when I use gluemnc to merge grid*.nc files?
Or is there any other/better method to merge the .nc file?

Thank you,
Xiao Xiao
