VI NOMENCLATURE OF FILES V1 1 Netcdf The products are stored using the NetCDF format NetCDF network Common Data Form is an interface for array oriented data access and a library that provides an implementation of the interface The netCDF library also defines a machine independent format for representing scientific data Together the interface library and format support the creation access and sharing of scientific data The netCDF software was developed at the Unidata Program Center in Boulder Colorado The netCDF libraries define a machine independent format for representing scientific data Please see Unidata netCDF pages for more information and to retrieve netCDF software package NetCDF data is Self Describing A netCDF file includes information about the data it contains Architecture independent A netCDF file is represented in a form that can be accessed by computers with different ways of storing integers characters and floating point numbers Direct access A small subset of a large dataset may be accessed efficiently without first reading through all the preceding data Appendable Data can be appended to a netCDF dataset along one dimension without copying the dataset or redefining its structure The structure of a netCDF dataset can be changed though this sometimes causes the dataset to be copied Sharable One writer and multiple readers may simultaneously access the same netCDF file VI 2 Add
