The Fortran-90 library provides current Fortran support for modelers and scientists.

The Fortran-90 interface is significantly simpler than either the C or Fortran-77 interfaces because of its use of overloaded functions and optional arguments.

• Write a two-dimensional array of sample data and read data from this file.
• Write some variables with units attributes and coordinate dimensions and read data variables and attributes from this file.
• Write some four-dimensional variables using a record dimension and read from the variables from this file.
