Hello, I'd like to advertise a hopefully useful new tool called 'cf2cf' for combining many CF-netCDF files into a single CF-netCDF file, where the input fields are aggregated into as few multidimensional netCDF variables as possible.
This is a command line utility which utilizes the proposed CF aggregation rules (trac ticket #78) to combine CF fields based on their metadata. In particular differing variables' units, dimension order, dimension direction and netCDF variable names are are accounted for in the aggregation process. A quick, simple example: % cf2cf -o one_output_file.nc lots_of_input_files*.nc All details, including full documentation, more examples and installation, may be found at http://www.met.reading.ac.uk/~david/cf2cf.html This tool uses the python cf package (http://code.google.com/p/cf-python), which also makes the same CF aggregation and the CF data model (trac ticket #68) available in an API, in a memory efficient manner. Any feedback, positive or negative, on cf2cf, the CF aggregation rules and the cf python package would, of course, be most gratefully received, to help make these better.
