NCO (Netcdf Operators): The NCO toolkit manipulates and analyzes data stored in netCDF-accessible formats, including DAP, HDF4, HDF5, and, most recently, Zarr. NCO exploits the geophysical expressivity and logic of many CF (Climate & Forecast) metadata conventions, the flexible description of physical dimensions translated by UDUnits, the network transparency of OPeNDAP, the storage capabilities (e.g., compression, chunking, groups) of HDF (the Hierarchical Data Format), many powerful mathematical and statistical algorithms of GSL (the GNU Scientific Library), and the lossy and lossless compression codecs provided by the CCR (Community Codec Repository). NCO is fast, powerful, and free.
NCO can be used to manipulate large data sets in NetCDF format. A faster and cleaner way than python or NCL scripts is to use command line operators that are specifically designed for climate datasets. NCO is a set of tools that allow this to be done easily. NCO is installed by default on all AOS computers.
