[ncl-talk] How to convert the value of a NetCDF file to zero

[Ehsan Taghizadeh]

Dear Setareh,I suggest you read the variables from the fout file again. For example, if there is a variable named "V10" in fout, you just need to read that variable from fout, as follows:V10_zero=fout->V10
This V10_zero has the same coordinates as V10 in the original file, but its values are zero.I hope this is correct.

 Dear Dennis,I noticed an issue. When I use the attached script it converts all values to zero, but the data is no georefrenced any more. So how can I fix this please?Thanks in advance.Best regards,

Dear NCL users,
I have a NetCDF file (attached) that contains some variables. I would like to change the values of all variables to zero for all grid points. So how can I do this using NCL, please?
This file is an input file for the WRF-Chem model, and I do not want to change the format of the file, only want to change the values to zero.
Please kindly advise me in this regard.
Thanks in advance.Kind regards,-- 
S.Rahimi
