You have a TDEF statement that indicates there are 96 time steps, yet you only provide chsub entries for the first three. I think you are on the right track with using %ch for the DSET entry — it’s not clear at all what the filenaming convention means — so just keep going with:
chsub 4 4 3B-HHR-E.MS.MRG.3IMERG.20150801-S013000-E015959.0090.V03E.HDF5
chsub 5 5 3B-HHR-E.MS.MRG.3IMERG.20150801-S020000-E022959.0120.V03E.HDF5
etc.
