3D baroclinic hydrodinamical and transport model Since FORTRAN codedSince FORTRAN coded Initial system: VAX/Open VMS: data is written in binary formatInitial system: VAX/Open VMS: data is written in binary format Later: VAX/ Open VMS with different word size: result: convert all the dataLater: VAX/ Open VMS with different word size: result: convert all the data Later again: (1993)Digital Alpha/NT result: convert all the dataLater again: (1993)Digital Alpha/NT result: convert all the data
3D baroclinic hydrodinamical and transport model Later again: Intel Pentium/NT result: convert all the dataLater again: Intel Pentium/NT result: convert all the data Enough: Let´s go to HDF: main advantages: portability, graphic tools that read it.Enough: Let´s go to HDF: main advantages: portability, graphic tools that read it.
The HDF Explorer ancestor:A graphical interface for the model Why do it ? 2 reasons:Why do it ? 2 reasons: The model has very specific features (sigma/ double sigma coordinate system)The model has very specific features (sigma/ double sigma coordinate system) The lack of a definite Windows based graphical softwareThe lack of a definite Windows based graphical software
Examples: model grids Examples: model grids
Examples: density fields (2d maps)
Examples: velocity fields, contours
