Although the netCDF data model and format are language-independent, all netCDF APIs are currently implemented over C or Java:

• NetCDF C interface developed in 1988
• Fortran-77 interface soon added as a thin layer over C library
• Unidata later developed interfaces for C++, Perl, Java
• A Fortran-90 interface was contributed, implemented over the Fortran-77 library
• Third-party C-based interfaces include Python, Perl, Ruby, NCL, Matlab, Objective C, Ada
