[netCDF #ULR-999382]: assistance with radar level 2 data

Hi,

As far as the units are concerned, those are available as the "units" attribute 
on the `RadialDatasetSweep.RadialVariable` object in the code you sent. Try 
adding this just after `varRef` is created:

    System.out.println("units: " + 
varRef.findAttributeIgnoreCase("units").getStringValue());

For how to visualize, the data are collected in a polar (well, technically 
spherical) coordinate system with the radar location at the origin. So exactly 
how much work you want to put into visualizing depends on your use case. The 
simplest is to take the azimuth angle (which is measured in degrees *clockwise* 
from 0, which is north) and range distance (calculated from the gate index 
multiplied by the gate size) together and get x,y relative to the origin as:

x = range * sin(az)
y = range * cos(az)

Hope this helps,

Ryan
