Gempak Graphics

This page is dedicated to Gempak and scripts to compile Gempak data.  I'm currently running Gempak scripts using the University of Oklahoma - School of Meteorology server (AKA fractal).  I hope to someday have a server setup with a NOAAPort feed at home.  I'd like to thank Dr. Laufersweiler and Mike James for continuing my Gempak education.
