Utilities
Data from this portal are available as NetCDF files. Information on this file format is available here and information on the OzFlux use of NetCDF files is available here.
There is a large range of options for viewing or reading the NetCDF files available from this portal.
Many of the applications commonly used for data processing (IDL, GDL, Python, MatLab, R etc) are able to read and write NetCDF files. OzFlux uses and recommends the Enthought Python DistributionM for manipulating the NetCDF data files available on this portal.
Libraries for reading and writing NetCDF files are also available for Fortran, C and other programming languages, see the UniData web site for details.
Various command line utilities are also available for viewing the contents of NetCDF files such as ncBROWSE and ncVIEW, see the UniData site for a complete list of third party software for use with NetCDF files.
OzFlux uses a suite of Python scripts to process the data from its flux towers. The scripts are available in the Public Access collection on the OzFlux Data Portal. Two of the scripts provide basic access to the NetCDF files. nclist.py provides a listing of the contents of a NetCDF file to the screen and to a text file that can be viewed in a suitable editor. nc2fn.py will read the contents of a NetCDF file and write selected data to a CSV (comma separated value) text file. This file can then be imported into any spreadsheet application.
An add-in that allows Excel to read and write NetCDF files is also available from here. The add-in only works with Excel 2007 and the 32-bit version of Excel 2010 but provides a convenient way to view and manipulate the NetCDF files available from this portal.
