CDL Files (original) (raw)
CDL is a data directory which contains examples of files that use the CDL format, a text file created by the NCDUMP program from a NETCDF file.
NETCDF (Network Common Data Form) is a set of software libraries and machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data.
Usage:
ncdump -h file.nc > file.cdl
reads the NETCDF file file.nc and prints out only the header information in CDL format.
ncdump -c file.nc > file.cdl
reads the NETCDF file file.nc and prints out the header information and the values of coordinate variables in CDL format.
ncdump file.nc > file.cdl
reads the NETCDF file file.nc and prints out the header information and the values of all variables in CDL format.

Sample Files:
For most of the following examples, the original NETCDF file is available in thethe NETCDF data directory.
- <foo.cdl>, a tiny example with named dimensions "lat", "lon", "time", and variables "z", "t", "p", "rh", "lat", "lon", "time", variable attributes "units", "_FillValue", "valid_range", and some data;
- <pres%5Ftemp%5F4D.cdl>;
- <sfc%5Fpres%5Ftemp.cdl>;
- <simple%5Fxy.cdl>;
- <x1.2562.grid.cdl> an MPAS grid file for a mesh on the sphere, using 2562 nodes, 5120 vertices, 7680 edges.
