[IDV #LTV-211426]: IDV and radar data



> Hello,

> I am trying to use IDV (v5.4 for a Win10 OS) to display radar data for

Hi David,

We can probably work out something to join the sweep files into a volume file, 
please
upload two or three sample sweep files you want to display as a volume:

I will give it a try and explain to you in more details.

In theory the answer is yes if the data format is what the IDV can handle. 
Again,
upload a sample for me to see what the problem is.

If it is a CF complaint netCDF file, there should be no problem.
