Hi Davie :

Yes, Rich is correct, and Im surprised that 3.17 worked..

Send me some sample files if you havent got this solved.

Roy & Dave,

I'm sure that John Caron will comment ono what changed, but doesn't
stuff in time aggregations need to understand time?   So one way to
fix it would be to add:

   <dimension name="ocean_time" orgName="time"/>

to your aggregation to rename your dimension "time" => "ocean_time".

So for example your aggregation would look like:

  <aggregation dimName="ocean_time" type="joinExisting">
        <dimension name="ocean_time" orgName="time"/>
             <scan

location="/home/om/dods-data/thredds/roms/eac/102/avg/"

                   suffix=".nc" />
          </aggregation>

Hi all,

I want to upgrade my TDS to 4.1 so I can serve compressed netcdf 4
files. I have tested it and it works great! However the upgrade to 4.1
breaks a couple of my aggregated datasets. The problem occurs when my
aggregating variable and it's dimension have different names. For
example my working dataset uses ocean_time(ocean_time) but the broken
ones use ocean_time(time). 3.17 works fine for either case but 4.1
(and probably 4.0) crap out with:

Error {
 code = 500;
 message = "AggregationExisting: no coordinate variable for agg
dimension=time";
};

The relevant section of my catalog is:

<dataset name="Averages"
       ID="eac_301_averages"
       urlPath="roms/eac/301/avg" >

 <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/
ncml-2.2">
    <aggregation dimName="ocean_time" type="joinExisting">
       <scan
             location="/home/om/dods-data/thredds/roms/eac/301/avg/"
             suffix=".nc" />
    </aggregation>
 </netcdf>
</dataset>

Any ideas? The earlier runs with ocean_time(ocean_time) are fine on
4.1 and 3.17.

Thanks,
David Robertson
