Folks,
If you like python, this seems like a perfect application for xray
(http://xray.readthedocs.org/en/stable/, which adopts a common data
model representation in python.
I found out about xray by reading this blog article:
https://ocefpaf.github.io/python4oceanographers/blog/2014/12/22/xray/
And I adapted it here to create a simple program that reads CSV data
using Pandas, converts to an xray Dataset, adds metadata, and then
uses an xray method to write to NetCDF:
http://nbviewer.ipython.org/github/rsignell-usgs/notebook/blob/master/csv2netcdf.ipynb
As Chris said, if you use the anaconda python distribution, you can
just do "conda install -c shoyer xray" to install xray.
