Hi Mike: Yeah, we have it working. Take a look at: http://oceanwatch.pfeg.noaa.gov:8081/thredds/catalogServices?catalog=http://oceanwatch.pfeg.noaa.gov:8081/thredds/aggreg/catalog.xmlWe have also tested it with matlab. There are 360 files I think in each case. One aggregates based on the file name, the other aggregates based on time inside the file. If you have questions as to how we did it, contact Jerome King at the email above. I have cc:'ed him.

I am using THREDDS 3.6, and like Bjørge Solli, I have been trying out the example aggregation code. When I initialize the catalog, I get no errors or warning in the catalog error file (with addition of dataType="Grid" to the dataset element).I am then able to select the "WEST-CONUS_4km Aggregation" dataset. However, when I select the Access: OPENDAP link, I get the error:Error { code = 1; message = "No data root for dodsC/satellite/3.9/WEST-CONUS_4km"; };In one of many attempted workarounds, I tried putting the ncml into its own file so I could access it through an <access> element. However, it appears that the <access> element ignores the dataFomat="NcML" attribute and tries to open the ncml as a netcdf and throws an error.If anyone has an example xml that uses netcdf aggregation elements please let me know... I really need this to work!BTW, my xml is:<catalog xmlns="http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0";xmlns:xlink="http://www.w3.org/1999/xlink"; name="THREDDS-IDD OPeNDAP Data Server" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0 http://www.unidata.ucar.edu/schemas/thredds/InvCatalog.1.0.1.xsd"; version="1.0.1"> <service name="ncdods" serviceType="OPENDAP" base="/thredds/dodsC/" /><dataset name="WEST-CONUS_4km Aggregation" ID="SSEC/IDD-Satellite/3.9/WEST-CONUS_4km-Agg" urlPath="satellite/3.9/WEST-CONUS_4km" dataType="Grid"><serviceName>ncdods</serviceName> <netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2";> <aggregation dimName="time" type="joinNew"> <variableAgg name="IR" /><scan dateFormatMark="WEST-CONUS_4km_3.9_#yyyyMMdd_HHmm" location="/data/ldm/pub/native/satellite/3.9/WEST-CONUS_4km/" suffix=".gini" /></aggregation> </netcdf> </dataset> </catalog>
