not sure where that error is coming from. send me more context if you want.

from http://unidata.ucar.edu/packages/dods/server/agg-html/agg_26.html
[...] A catalog element contains exactly one top-level dataset. [...]

The example you gave me had the structure:
<catalog...>
      <service.../>
      <service.../>
      <dataset..>
            <property.../>
            <dataset...>
            </dataset>
      </dataset>
</catalog>

Since the catalog did not have exactly one dataset element, I changed the structure to:
<catalog...>
      <dataset...>
            <service.../>
            <service.../>
            <dataset..>
                  <property.../>
                  <dataset...>
                  </dataset>
            </datset>
      </dataset>
</catalog>

sorry, looks like i just cut and pasted incorrectly

if the dods url is in the NcML, use dods: instead of http:

This worked, thanks, I was able to access the aggregated dataset with Ferret.

the Data Request Form link again appears as
http://stout.pmel.noaa.gov:8180/TestNcML.xml.html

when we need
http://stout.pmel.noaa.gov:8180/dodsC/TestNcML.xml.html

when i do it from here, i get:

http://stout.pmel.noaa.gov:8180/dodsC/TestNcML.xml.html

I used the full path and three slashes in the stdmet service base attribute, file:///. I have cleared browser caches and stop/started the server again. No change. This may be TOMCAT and not the Agg Catalog.

what version tomcat? might need upgrading?

BTW, there is some info at

http://stout.pmel.noaa.gov:8180/dodsC/debug

that i havent documented, but might be useful anyway

Thanks for your help. I will begin larger aggregations and add lon/lat axes tomorrow. How would I add a global attribute?

<netcdf ...>
 <nc:attribute name="scale" type="double" value="1.2"/>
