I have multiple Grib files, each holding a separate time. How do I animate these?
A. Normally the IDV does not try to merge the separate grid files, it just loads them up individually as separate data sources. You then have to create separate displays for each time step. Furthermore, in the IDV displays with just one timestep are always shown. What you want to do is to select the multiple set of grib files in the File Chooser (using control or shift click) and then select “Aggregate Grids by Time” for the Data Source Type. This will try to aggregate the grid files on time and will produce one data source with a set of times. Note: each grib file needs to be identical in terms of variables, projections, etc. They should only differ by time.
