NetCDF (Network Common Data Form) is a set of software libraries and self-describing, machine-independent data formats that support the creation, access, and sharing of array-oriented scientific data. It is widely used in atmospheric, oceanographic, and climate science, as well as in other fields that deal with large datasets of numerical data. NetCDF files can store variables, dimensions, and attributes, making them a flexible and powerful way to organize and represent complex scientific data. The format is designed to be portable across different platforms and programming languages, ensuring that data can be easily shared and analyzed by researchers using different systems. NetCDF supports various data types, including integers, floating-point numbers, and characters, and it allows for the creation of multi-dimensional arrays. The self-describing nature of NetCDF files means that the data is accompanied by metadata that describes the structure and meaning of the data, making it easier for users to understand and interpret the data without needing external documentation. NetCDF is an open standard, and the libraries for reading and writing NetCDF files are freely available.
