Re: Another question about how can i know what the missing valuesis defined in a Netcdf data file?

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Gao,
You can see what value Ferret is using for missing values with the command

   say `varname,return=bad`

For variables in netCDF files, if you want to use a different value than this for the missing numbers, say 999, then you can use

   set var/bad=999 varname

The discussion in the Users Guide under "SET VARIABLE /BAD" tells what Ferret does with the "missing_value" and "_FillValue" attributes in NetCDF files.

Hi, sorry to disturb you all again.

 

I found my gridded NetCDF data file including missing values when i plot a time series. How could i get the value defined for them under Ferret?

 

Thanks, Gao
