[ncl-talk] Save in netcdf

[Karin Meier-Fleischer]

Hi Soma,

please, reply always to ncl-talk that everybody is able to follow.

The problem is, that you changed the name of the level dimension to lev. 
ZMT has the dimension name level. Change lev to level and it should work or

ZMT!1    = "lev"
ZMT&lev = lev
