NCDateien

NCDateien, also known as NetCDF (Network Common Data Form) files, are a set of interfaces and self-describing data formats that support the creation, access, and sharing of array-oriented scientific data. Developed by the Unidata Program at the University Corporation for Atmospheric Research (UCAR), NetCDF is widely used in fields such as meteorology, oceanography, atmospheric science, and climate research. Its primary purpose is to facilitate the exchange of scientific data among different research groups and computer systems.

The NetCDF format allows scientists to create data files that are independent of the machine or operating system on which they are created. This portability is crucial for collaborative research and for ensuring long-term data accessibility. A NetCDF file is organized into three main sections: dimensions, variables, and attributes. Dimensions define the shape and size of arrays, variables represent the actual data points, and attributes provide descriptive metadata about the data, such as units, descriptions, and origins.

The self-describing nature of NetCDF files means that all the information needed to interpret the data is contained within the file itself, eliminating the need for separate documentation. This makes it easier for users to understand and utilize data created by others. Libraries are available in various programming languages, including C, Fortran, Python, and Java, to read and write NetCDF files, further promoting its widespread adoption in the scientific community.
