[Support #NAB-494698]: Mcidas--Grids not available?

OK, gotcha.

OK.

So, it may be quite easy for you to change from the old RTGRIDS datasets to
the new RTGRIBS datasets.  If you are game, I would ask you to make a
copy of one of your scripts and make the change to test things out:

change:

- ADDE group from RTGRIDS -> RTGRIBS
- GFS -> GFS-ALL
- NAM -> NAM-ALL
  etc.
- add DATALOC for RTGRIB server: idd.unl.edu, adde.cise-nsf.gov, or 
stratus.al.noaa.gov:

  DATALOC ADD RTGRIBS IDD.UNL.EDU


Everything else should work the same.  After all, it is the same model data
that is being ingested and processed.  The only difference is how the
data is being processed; the group name of the ADDE server that hosts the
data; and the partitioning of the data into datasets.

For comparison, in the "old" (v2006 and previous) way of putting fields
into datasets, there were:

DSINFO GRID RTGRIDS

        Dataset Names of Type: GRID  in Group: RTGRIDS
Name         NumPos   Content
------------ ------   --------------------------------------
ALL           1310    Real-Time Grids

GFS            300    Real-Time GFS/AVN Grids

RUC             80    Real-Time RUC Grids
UKMT           110    Real-Time UK Met Grids

DSINFO -- done

With the GRIB filer method (using a MySQL database), this has changed to:

DATALOC ADD RTGRIBS IDD.UNL.EDU

Group Name                    Server IP Address
--------------------         ----------------------------------------
RTGRIBS                      IDD.UNL.EDU

<LOCAL-DATA> indicates that data will be accessed from the local data directory.

DSINFO -- done

Notice that in the new scheme, there is always an all-inclusive set of any
type of data: ALL, GFS-ALL, RUC-ALL, NAM-ALL, etc.  These sets _should_
correspond 1-to-1 with the old RTGRIDS sets: ALL, GFS, RUC, NAM, etc.

> Thanks again, and sorry for all the hassle.

You are welcome, and this is not a hassle (outside of finding and fixing
a bug).

Cheers,

Tom
