Hi Don, I see the same thing. For example, if we compare the "best" for the GFS 1.0 degree for 2013-09-08 18Z, 21Z with the 2013-09-08 run using 18Z (analysis), 21Z (3 hour forecast) the grids turn out to be different (I'm comparing MSLP_Eta_Model_Reduction), even though they *should* be the same. Lansing pointed me to a jira ticket that describes something similar, except it comes from an FMRC rather than a GRIB feature collection: https://bugtracking.unidata.ucar.edu/browse/TDS-470 I'm going to check a few other "best" collections to see if the same thing is occurring elsewhere when the catalog is not partitioned by time.
