Just for fun, I downloaded a two-month time-series of a spatial subset of ds083.2, FNL, for 20141201 through 20150131. Because I don't want to open up each file individually, I used the concatenation technique I mentioned in What is GRIB2?
cat fnl*spasub* > movie.grib2
|244 files can be merged into one file for movie-making mayhem.|
Set up your Panoply window for optimal viewing. In this case I clicked on the Map tab and selected the 'Equirectangular (Regional)' Projection from the menu.
Then click on the Data tab and enable 'Always fit to data'.
Go back to the Array(s) tab, and click on an arrow in the 'GRIB reference time' to step forward or backward. You just made a movie using binary GRIB2 files.
