netcdf_test

netcdf_test, a C++ code which uses the NETCDF library and file format.

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.

For some reason, the C++ version of the NETCDF user guide does not include any examples of programs whatsoever. One has to infer what to do based solely on the description of the classes. The example programs in this directory are supplied by the NETCDF implementors, and must serve as partial, though scantily documented, substitutes for the missing information in the user guide.

Examples and Tests:

SIMPLE_XY_WR writes data to a NETCDF file. The data is a simple two-dimensional array.

• simple_xy_wr.cpp, the program;
• simple_xy_wr.sh, runs the test;
• simple_xy_wr.txt, the output file.
• simple_xy.nc, the NETCDF file created by the program.
• simple_xy.cdl, the CDL text file version of the NETCDF file.

SIMPLE_XY_RD reads data from a NETCDF file.

• simple_xy_rd.cpp, the program;
• simple_xy_rd.sh, runs the test;
• simple_xy.nc, the NETCDF file to be read.
• simple_xy_rd.txt, the output file.

SFC_PRES_TEMP_WR writes data to a NETCDF file. The data will include units attributes and coordinate dimensions.

• sfc_pres_temp_wr.cpp, the program;
• sfc_pres_temp_wr.sh, runs the test;
• sfc_pres_temp_wr.txt, the output file.
• sfc_pres_temp.nc, the NETCDF file created by the program.
• sfc_pres_temp.cdl, the CDL text file version of the NETCDF file.

SFC_PRES_TEMP_RD reads data from a NETCDF file.

• sfc_pres_temp_rd.cpp, the program;
• sfc_pres_temp_rd.sh, runs the test;
• sfc_pres_temp.nc, the NETCDF file to be read.
• sfc_pres_temp_rd.txt, the output file.

PRES_TEMP_4D_WR writes data to a NETCDF file. The data will be four-dimensional and use a record dimension.

• pres_temp_4D_wr.cpp, the program;
• pres_temp_4D_wr.sh, runs the test;
• pres_temp_4D_wr.txt, the output file.
• pres_temp_4D.nc, the NETCDF file created by the program.
• pres_temp_4D.cdl, the CDL text file version of the NETCDF file.
