Steve Hankin was looking at specifying a CSV format that would map to
netCDF.

I'm not sure what came of that.

In the meantime, how to do this now depends on what tools you are familiar
with:

I would use Python (and probably xarray) to write a translator -- it would
be quite straightforward if you are familiar with Python.

Other options are:
- Any number of other programming languages
- some way to translate to CDL -- given that the meta data is similar for
all this data, that could be not too hard.
