[ncl-talk] multiple asc files

[Dennis Shea]

[1] "using the "do" (loop) I was trying, but I need to open all files at
once. As *systemfunc* + *addfiles*."

No. *addfiles*
<http://www.ncl.ucar.edu/Document/Functions/Built-in/addfiles.shtml> does
not work with ASCII/text/cvs/.... files.

[2] "And how could I save a new asc with this coordinate information from
the head?"

You must manually extract appropriate information and construct the
appropriate arrays.
ASCII/text can be messy. The user must think how to read data in some
appropriate form.
There is no generic 'read an arbitrary ascii file and generate appropriate
information' ... in any language.'
This becomes user responsibility! This is why the netCDF and HDF file
formats are useful.

[3] "Is this possible just reading one by one?"

Yes, of course. However, the user must think how to do it.
========================================================
Over the years, ncl-talk has answered many ASCII read questions.
It is not difficult. However, the user must construct the appropriate
constructs.

Attached, is a basic example.

I saved as netCDF. If you want to save as ascii ... you will have to write
the code.

Perhaps, *you* will have to make some changes for lat/lon.

Good luck
