[ncl-talk] re-order array by time dimension

[Mary Haley]

Hi Andrew,

It would help if we could see a sample of your files so we can understand
how the time dimension is getting out of order.

Can you provide a subset of them or even all of them? I can see that there
might be issues when you are talking about data that is being collected at
the seconds level.

If you just have a few files, or if they are not too large, then you can
use our ftp:

    ftp ftp.cgd.ucar.edu
    <log in as "anonymous">
    <Use email address as password>
    cd incoming
    put <your files>
    quit

You can do this offline if you prefer.

Thanks,

--Mary
