Re: [ferret_users] Re: Save the time dimension data

Dear Atul,

In order to append two files, you need to have a record dimension, which is generally the time axis. So, the easiest option to append two files is through time axis and not the depth axis. (However, it is possible to do other way, in such case you need to convert the depth axis as record dimension; see NCO commands for this)

Here, is an example to append a variable over its time axis:

sp rm -rf outfile.nc

repeat/l=1:73 (save/file=outfile.nc/ap uvel)

Hope it may help,

Abhisek
