[Support #TKA-168856]: Aggregating NARR GRIB Files

Hi Bradley-

The aggregation by time requires that each file have only 1 forecast hour (the 
analysis) for it to work.  These files seem to have multiple times in them.

The only solution at this point is to load all the files in as Grid Files (you 
can select multiple files in the chooser).  You can then create time animations 
using the
Miscellaneous->Make a time sequence from single time grids/images formula in the
Formulas data Source.  Select the type of display you want and when the Field 
Selector appears, select the field you want from each file and click the Add 
Selected.  When you've selected all the grids, click the OK button.

It's a pain, but it should work.
