Hi Jason- We do not support loading in data from a web server. You can load in data either from local disk or through a THREDDS Data Server (TDS). I know that Purdue was experimenting with the TDS, so you might want to contact them to see if they support access through that method. Otherwise, you can right click on a file and download it to your local disk and then use the IDV to view it.
