From the developer:
WINGRIDDS is a Microsoft Windows 32-bit implementation of the DOS-based PCGRIDDS application. The program allows the user to view meteorologically significant fields of gridded observation analysis and numerical weather prediction model output (GRIB files). The fields are displayed in either contour or vector format, whichever is appropriate for a particular field.
