The IDV provides a scripting facility called ISL (IDV Scripting language): http://www.unidata.ucar.edu/software/idv/docs/userguide/isl/index.html How this is usually used is to create what you want to see in the IDV and write it out as a ".isl" file. This is really a convenience for the user. This will write out the IDV bundle file and also a .isl file. The isl file can then be used by the IDV for both onscreen and offscreen generation of image and movie products. The generated isl file loads in the bundle and then generates an image or movie. Your situation is a little stickier because you have a set of files that need to be aggregated and are created all of the time. The easiest approach would be to load the IDV with all of the files as an aggregated grid data source (which aggregates any number of files on time). Or you could write out one large grib file and load that in. You could then write out a bundle and isl script that generates the images. However, you would need to have the files be in the same directory (if idv does the aggregation) and have the same names. The isl facility does have the ability to change the files that are referenced in the bundle it loads.
