[Wrf-users] joining binary files into one file

[Abraham]

Thank you very much Eric
Abra

You cannot use 'cat' to combine binary files. The resulting file will not have the correct
 structure. You need to use a fortran or C program to read all of the data in each file, then
write that
 data into one file (in the proper order). You need to know how the input files were written in
 order to correctly read the data in a program.

There is one situation where you CAN use 'cat' to combine data files, and that is if they are in
 GRIB format. (I'm not sure if it works with GRIB-2 files.) But you can't do this with binary or
 netcdf files.

Subject: [Wrf-users] joining binary files into one file

Hi wrf-user, 

Does any one know how to combine some binary files (each file contains one time step data) into
one file without affecting the data's order. I tried to use cat to join them and it does combine
them but the data is not organised.For instance, when I try to desplay v field using grads, height
h is desplayed.
 
Your assistance will be appreciated
thanks
