One problem with using Web Start to start the IDV is that you probably missed the instructions on "Downloading and Running the IDV" in the User's Guide: http://www.unidata.ucar.edu/content/software/idv/docs/userguide/Starting.html There you'll find it takes about 70 Mbytes of disk space. It's also possible to have a double-clickable IDV icon on your desktop to start it up, but I think only got that when I use the InstallAnywhere installer. Sorry, but I can't remember how I got that double-clickable icon, but when I get info on it, it says it's an Application (which on Mac OS X means it's a folder named 'Integrated Data Viewer.app') of size 108 KB. To connect to data sources, just follow the instructions in the "Data Sources and Formats" section of the User's Guide: http://www.unidata.ucar.edu/content/software/idv/docs/userguide/data/DataSources.html You can also get data from local files if it's in netCDF form that follows the conventions supported by the IDV (COARDS, CF, or NUWG), but one of the IDV's strengths is its ability to access remote data, including small subsets of large datasets on remote servers. So for ADDE data, for example, you have to be connected to a server. By the way, there's currently a workshop for IDV going on that you can access via a webcast: To participate, you will need the latest version of RealPlayer.
