Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

A property of netCDF data is that a file created by the interface in one language, for example Java, should be readable by the API of any other language, for example Fortran-77. The latter language doesn't actually support variable-length strings, so it's difficult to write an API for Fortran-77 that could deal with attributes that were arrays of variable-length strings. Many of the netCDF's limitations derive from the requirement that Fortran-77 programs must be able to read all netCDF datasets. --Russ
