Greetings!
I'm currently working on a program to do such a thing. Basically you would
need to define the layout of your file (like you've done below) in a
point-and-click way, and then run the converter by pointing it to the top
directory of where you ASCII files live. This code, however, is very much
alpha.
When you do make the netCDF files, I would suggest that you make sure to
try and follow CF conventions. Note that your data would likely be
classified as a "Trajectory of Profiles." To see what you would need to
do to make your netCDF files CF compliant, check out Section A9.6 in the
following document:
http://www.unidata.ucar.edu/staff/caron/public/CFch9-may10.pdf
I have not implemented the Trajectory of Profiles convention in my
converter yet (again, it's a very rough alpha), but it may be the next
thing I try to add.
Cheers!
Sean
