Hi Joe:
It looks like the main problem is that you want to use "JoinExisting" on
the variable time, rather than "JoinNew", so:
<aggregation aggType="JoinExisting" serviceName="NAVO" varName="time">
<fileAccess urlPath="mcsst_k10_20030806.nc"/>
...
the coord values are taken from the existing time variable, so you wont
need the coord attribute; also i removed the serviceName, since they all
come from the same service, which can be specified in the aggregation
element.
There may also be a bug with the "null" attribute for JoinNew, which I
will check. However, I think the above will solve your problem. let me
know if it does.
Also, I think we still need to upgrade the AS war file in order to do
some NcML based buoy data, yes? I will try to get a new AS made today
that you can start using for that purpose...

Hi Roland,
(John, this will better explain the problem I sent to you in 28AUG 17:13 email)
Here is what is going on. In composing this I narrowed the problem down to the
DAS
output.
The two cdl outputs from dncdump -h show the problem.
Both servers use copies of the same AggServerCatalog.xml
The first one is good, it comes from the server which you set up.
I copied all of your files and put them on stout at
/usr/local/www/html/tomcat/webapps/dodsC/
the Aggregation Server creates the axis time1 and gives it units.
The second cdl output is from the aggregation server on stout at
/usr/local/www/html/TOMCAT_DEMO/las/las_servlet/jakarta/webapps/dodsC/
time1 has no units, and Ferret gets no time information.
The problem must lie in the difference between the two .das outputs
good:
