Hi Rich,

I'm not getting the inconsistent array length message but I'm having trouble 
reading the data. Sometimes it just says it can't read it and other times it 
has an IO error (this is actually from IDV but I got the same thing in ToolsUI):

java.io.IOException
        at ucar.nc2.dods.DODSNetcdfFile.readArrays(DODSNetcdfFile.java:1165)
        at ucar.nc2.dods.DODSNetcdfFile.<init>(DODSNetcdfFile.java:289)
        at ucar.nc2.dataset.NetcdfDataset.acquireDODS(NetcdfDataset.java:592)

        at ucar.nc2.dataset.NetcdfDataset.acquireDataset(NetcdfDataset.java:409)

        at ucar.nc2.dt.grid.GridDataset.open(GridDataset.java:71)

The DAS and DDS look fine as does a .ascii request for lat, lon, time, and 
depth. But when I request tau

http://coast-enviro.er.usgs.gov/thredds/dodsC/ncom/test.asc?tau

I get this error message

Error {
    code = -1;
    message = "NcSDArray ArrayIndexOutOfBoundsException=null";
};

Is this an aggregated dataset? If so, can you send us the NcML that specifies 
the aggregation?

Where does tau come from? I notice that it isn't used as a coordinate variable 
by any of the data variables.

Thanks,

Ethan
