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.
