NETCDF
Reading and Writing NETCDF Files

NETCDF is a directory of MATLAB programs which illustrate the use of 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.

Languages:

NETCDF is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a MATLAB version.

Examples and Tests:

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

• simple_xy_wr.m, the program;
• simple_xy_wr_output.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.nc, the NETCDF file to be read.
• simple_xy_rd.m, the program;
• simple_xy_rd_output.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.m, the program;
• sfc_pres_temp_wr_output.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.nc, the NETCDF file to be read.
• sfc_pres_temp_rd.m, the program;
• sfc_pres_temp_rd_output.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.m, the program;
• pres_temp_4D_wr_output.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.

PRES_TEMP_4D_RD reads data from a NETCDF file.

• pres_temp_4D.nc, the NETCDF file to be read.
• pres_temp_4D_rd.m, the program;
• pres_temp_4D_rd_output.txt, the output file.
