求助用ncl创建nc变量的问题

X1a0wu

目前使用addfile("xxxx.nc","c")的命令创建nc变量，但是会有2gb内存的大小限制，如果想要创建大于2gb储存的nc文件应该怎么设置呢

用这个setfileoption("nc","Format","LargeFile")

HI Bill,
Standard NetCDF has a size limit of 2GB per file. There is a large
file option that allows much larger files. You can set this option
using NCL's setfileoption:
setfileoption("nc","Format","LargeFile")
You must do this prior to creating the file in NCL.
There are still some size restrictions with this mode. To remove
virtually all size restrictions you can use the NetCDF4 format;
setfileoption("nc","Format","NetCDF4Classic")
More information can be found at http://www.ncl.ucar.edu/Document ... setfileoption.shtml
