Though the first two datasets listed in the aggregation are not accessible. Is this a rolling archive and does your aggregation catalog get updated? Here are the two datasets I can't access: http://edac-dap.northerngulfinstitute.org/dods-bin/nph-dods/NCOM/region1/ncom_glb_reg1_2008070500.nc http://edac-dap.northerngulfinstitute.org/dods-bin/nph-dods/NCOM/region1/ncom_glb_reg1_2008070600.nc Another interesting thing I noticed is that the OPeNDAP representation makes tau a grid with time the coordinate variable. Which makes sense given that time(time) is a coordinate variable and tau(time) uses the same dimension. Just wondering if that might cause any problems in the aggregation.
