[NCO] change variable name, “rename”

cited from here

I often use this command when the axis format of data is difference which CDO cannot recognize.

(ex: the axis name, “X136_360”, can not be recognized in CDO, but “X” can.)

 

This is handy when you obtain a file with unfortunate choices of variable, dimension, or attribute names.

ncrename -h -O -v old_variable_name,new_variable_name filename.nc

-h: do not add to the history variable
-O: (upper case) overwrite the file.
-d oldname,newname: to change a dimension name
-a oldname,newname: to change an attribute name
