"Gtool5": a Fortran90 library of input/output interfaces for self-descriptive multi-dimensional numerical data.

The article presents a study which develops a Fortran90 input/output library called gtool5 for use with numerical simulation models in the fields of earth and planetary sciences. In this study, the use of this library will simplify implementation of input/output operations into program code in a consolidated form independent of the size and complexity of the software and data. Moreover, this library enables simple specification of the metadata needed for postprocessing and visualization.
