[las_users] Not a valid CDM File question.

Hello,

I'm sending this both to the THREDDS and LAS mailing list and hope to get an advise on a solution.

I created a THREDDS catalog that dynamically aggregates the NetCDF files to a virtual netcdf..

The configuration works great when accessing via THREDDS URL.

I then used the THREDDS/Opendap link of the Virtual NetCDF file to configure the dataset into LAS.

When accessing the dataset in the Interface, there are no messages returned in the LAS log nor TOMCAT directory.

I did notice when selecting the (?) from the LAS dataset selection, I selected the .jnl link and it returned:

Error {

    code = 500;

    message = "java.io.IOException: Cant read /usr/local/tomcat/content/las/conf/server/data/SSHA_TEST/data_podaac-ecco.jpl.nasa.gov_thredds_dodsC_kf080_kf080_have_timeAgg.nc.jnl: not a valid CDM file.";

};

QUESTION: How can I make the virtual NetCDF file to be a valid CDM file. Note I used joinExisting because each granule contains more than 1 time value (from 3 to 10). and using joinNew requires only 1 time entry per granule.

THREDDS/OPeNDAP link to aggregated dataset:

Main THREDDS Catalog:

Here's the Snippet configuration of the aggregated dataset. You can also find the scan location directory content here:

(catalog.xml) - a snippet of the dataset.

</aggregation>

</variable>

</variable>

</variable>

</netcdf>

Here's the first part of the aggregated NetCDF file it generated and placed in THREDDS ./cache/agg/kf080-kf080_have_timeAgg.nc

<?xml version='1.0' encoding='UTF-8'?>

</netcdf>

</netcdf>

</netcdf>

</netcdf>

</netcdf>

Here's the Access in the LAS interface

http://podaac-ecco.jpl.nasa.gov/las/

select (kf080_have) -> Sea Surface Height (it'll just hang). Select (?) next to the dataset name and click on .jnl you'll find the error message.

Please advise.

Thanks so much.

Rosanna.
