[ncl-talk] _FillValue directly from a file variable

[Toni Klemm]

Hi Mateus,

I imagine there are more elegant ways, but if you don’t have too many files (or if they have the same variable type (int, float, …), you can run the command 

ncdump -h file/path/and/filename.nc

which will give you the metadata to each variable, and copy-paste the _FillValue value of your variable directly into your NCL script. Another way is to view the file in a viewer like Panoply and get the _FillValue that way.

Hope that helps,
Toni
