About NCO
The NCO toolkit manipulates and analyzes data stored in NetCDF-accessible formats, including DAP, HDF4, and HDF5. It exploits the geophysical expressivity of many CF (Climate & Forecast) metadata conventions, the flexible description of physical dimensions translated by UDUnits, the network transparency of OPeNDAP, the storage features (e.g., compression, chunking, groups) of HDF (the Hierarchical Data Format), and many powerful mathematical and statistical algorithms of GSL (the GNU Scientific Library). NCO is fast, powerful, and free.

Typical applications at BAW
Concatenation of several NetCDF files converted from boewrt.dat files into one cf-netcdf.nc file
- Convert several boewrt.dat files using DATACONVERT to equivalent cf-netcdf.nc files;
- With ncrcat several files can be concatenated into one cf-netcdf.nc file;
- Typical post processors: NCANALYSE;
- Example: ncrcat -h f1.nc f2.nc ... fn.nc result.nc (-h suppresses the modification or creation of a history attribute);
- More information: ncrcat-netCDF-Record-Concatenator.
