Hi Massoud, re: > Do you know by any chance what the grid size (i.e., row x column) is for > the GOES IR composite image? > > http://www.unidata.ucar.edu/software/gempak/images/gemweb.gif The GIF itself is 800x1000. The underlying image appears to be the Super National IR composite from NOAAPORT whose size is 1008x1536. I would assume that the grid size that Chiz works with is the same size as the original image, so my best guess is that the grid is 1008x1536. Its a shame that your schedule did not allow you to attend the GEMPAK training workshop since Chiz is going into detail about how to create these kind of things in it this week (yesterday, today, and tomorrow). > Thanks for your time. No worries. Cheers, Tom **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
