this should work: <?xml version="1.0" encoding="UTF-8"?> <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";> <variable name="ntime" type="int" shape="ntime"> <attribute name="units" value="days since 1990-01-01 00:00:00"/> <attribute name="_CoordinateAxisType" value="Time" /> <values>4602 4607</values> </variable> <aggregation dimName="ntime" type="joinNew"> <variableAgg name="sea_level"/> <netcdf location="http://dods.jpl.nasa.gov/dods-bin/nph-nc/pub/data_collections/woce_v3/topex/data/10_deg/ssh10d20020808.nc.gz"/> <netcdf location="http://dods.jpl.nasa.gov/dods-bin/nph-nc/pub/data_collections/woce_v3/topex/data/10_deg/ssh10d20020813.nc.gz"/> </aggregation></netcdf> your main problem was using a "," in <values>, which was silently failing. also you need to specify type="int". I also discovered 2(!) more bugs in the convention parser, which you probably wont see.
