Hi Katherine,

Yes, that can be done. Your attempt is failing due to a small problem with your 
datasetScan elements. The path attribute values must be unique. (This is true 
across a TDS. Meaning that each path attribute for all datasetScan and 
datasetRoot elements in all config catalogs for a TDS must be unique.) The 
reason is that the path value is how the TDS matches an incoming request URL to 
a particular datasetScan. I'm including my changes to your example below. 
Notice also that I'm changing the ID value as well (dataset IDs have to be 
unique in a catalog but it is convenient to have the ID match the path in 
datasetScans).

> <datasetScan name="My Pressure Level Data"
>      ID="ecmwf19972001"
>      path="ecmwf19972001"

     ID="pLevel-ecmwf19972001"
     path="pLevel-ecmwf19972001"

>      location="/data/ecmwf19972001/" harvest="true">
>   <filter>
>     <include wildcard="ggap*.nc" />
>   </filter>
> </datasetScan>
> <datasetScan name="My Surface Data"
>      ID="ecmwf19972001"
>      path="ecmwf19972001"

     ID="surf-ecmwf19972001"
     path="surf-ecmwf19972001"

>      location="/data/ecmwf19972001/" harvest="true">
>   <filter>
>     <include wildcard="ggas*.nc" />
>   </filter>
> </datasetScan>

Hope that makes sense.

Let me know if you have any other questions or run into other problems.

Ethan
