Greetings!

It depends on which viewer you are trying to access. Godiva2 is a javascript
based, in browser visualization tool that should work with any browser released
in the past 5 years or so. If you are trying to use the "NetCDF-Java ToolsUI
(webstart)" or "Integrated Data Viewer (IDV) (webstart)", you will need to have
Oracle Java 8 installed on the system. Those links will download a .jnlp file,
which will need to be executed using the javaws.exe program that comes with
Oracle Java 8. Note that Webstart has been deprecated as of Java 9, and and is
no longer available as of Java 11. As such, future version of the THREDDS Data
server will no longer list webstart based viewers.

If you do want to use the IDV to view the datasets, you can download and install
the IDV application locally:
