Guys,
I think once we know its a Curvilinear Orthogonal, we should identify the 2D
lat, lon fields and use them, without needing NcML.
If there is a general way to do this, by all means yes! The lon/lat
records might not be there, however. In one case the provider had the
data variables in one collection of grib files, and the lon/lat values
for the grid in another grib file.

Hi Rich:
We have this pretty much working. The GRIB layer now recognized the
orthogonal curvilinear grid type and does the right thing. this allows
simple fmrc aggregation to work, eg:
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2">
<aggregation dimName="runtime"
type="forecastModelRunSingleCollection" timeUnitsChange="true"
recheckEvery="10min">
<scanFmrc location="./" regExp=".*ofs_atl.*\.grib2$"
runDateMatcher="#ofs.#yyyyMMdd"
forecastOffsetMatcher="HHH#.grb.grib2#" subdirs="true"
olderThan="10 min"/>
</aggregation>
</netcdf>
Im running unit tests now, I can make a release at the end of the day
for you to try, assuming its not too late for you to use.
The 2D lat/lon adds some extra time, so its a bit slow. At some point Im
going to look at 2D lat/lon to see if theres some speedup to be had
somewhere.
