Hi Noelia,<br>
<br>
NCL can't create a new file when it already exits. You have to make
sure that the file doesn't exist or delete it before using addfile.<br>

<div>I have hourly files from WRF and I wanted to create daily
files (with the hourly outputs, Time=24). I was using
addfile(, "c")....I know the error I got it is caused by "c",
once the first file is created I can´t opened again..(If I am
not wrong, right?) Is there any way to do it?</div>
