Re: [ferret_users] combine data

[David Wang <climater@xxxxxxxxx>]

Hey Seontae,

It's not necessary to glue all your 10 netcdf files into one. You can 
actually create a description file (say, sst.des) for a series of netcdf 
files and access them through it in ferret. Here is the script that will 
create a description file for you (thank Andrew):

The code is pretty much self-explaining.
