Re: phone message -- sample XML to follow (here it is)

Hi Kevin, Steve:

You should try putting the ncoords attribute on the outer aggregation:

             <netcdf
             xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";
             ncoords="36500">
               <aggregation type="union">
                  <netcdf
                  
location="file:/data/gfdl_cm2_0/CM2Q-d2_1PctTo4x_j1/pp/atmos/ts/daily/pr_A2.00010101-01001231.nc"
                  />
                  <netcdf
                  
location="file:/data/gfdl_cm2_0/CM2Q-d2_1PctTo4x_j1/pp/atmos/ts/daily/tasmax_A2.00010101-01001231.nc"
                  />
                  <netcdf
                  
location="file:/data/gfdl_cm2_0/CM2Q-d2_1PctTo4x_j1/pp/atmos/ts/daily/tasmin_A2.00010101-01001231.nc"
                  />
               </aggregation>
             </netcdf>

let me know if that helps.

Id like to test this nested aggregation as a use case . Can I get those 9
files? thanks.
