EZcdf

Abstract
EZcdf is a high-level, easy-to-use interface to the NetCDF library (http://www.unidata.ucar.edu/packages/netcdf), a file format which allows one to write/read binary files across architectures without regard to the underlying native byte ordering. NetCDF is language independent; files can be written in a programming language (e.g. Fortran, C, Java, Python, IDL) and read in another. Data can be accessed randomly so that the content of a NetCDF file can evolve without compromising backwards compatibility.
Unfortunetely, the complexity of NetCDF has deterred many users in the past. While EZcdf does not support the full capability of NetCDF, it is almost as simple to write a NetCDF file with EZcdf as using unformatted read/write instructions. At present, EZcdf only supports finite sized arrays of rank <= 3. On the other hand, EZcdf accepts complex and logical data types, which are mapped to real, respectively integer, arrays while providing a name mangling mechanism to overcome the lack of support for complex and integer types in NetCDF.
EZcdf's first application was to replace BZIO calls in many PPPL codes such as JSOLVER, DMAP, PEST and others.
