Re: [las_users] Error when requesting Difference Mode plots with LAS v8.4

This is just a problem of configuration with the THREDDS server associated with the LAS. If you recently upgraded your TDS then there are certain configuration steps that must be re-done for the TDS to work with LAS.  The details are here: http://ferret.pmel.noaa.gov/LAS/documentation/installer-documentation/installation/installing-and-integrating-tds-with-las/.

In particular, the section about adding the dataSource and nj22Config XML tags to threddsConfig.xml are likely relevant since these must be added for THREDDS to understand that a .jnl file created by LAS can be interpreted as CDM file.

After displaying two plots from the same dataset, clicking the Difference Mode button generates the following error:

If the dataset is accessible to create the compare 2 plots, any ideas why creating the difference plot fails?

To recreate this error, go to mynasadata.larc.nasa.gov, click 'Explore NASA Data", "Advanced LAS", Dataset, Atmosphere, Atmospheric Temperature, Monthly Near-Surface Temperature(ISCCP), Compare 2, select two different dates, and click Difference Mode.  (Thredds version is 4.3.23 –20140826.1617).

Any ideas how to work around this?
