[IDV #JIN-167233]: unablr to read Indian DWR data file

> Dear Unidata Support,
> 
> I have uploaded the Archive.zip contains 22 files, 20 files are single 
> sweeps, and 2 files named as polar_*.nc are cfradial files created from those 
> 20 single sweep files using PyScanCf 
> (https://github.com/syedhamidali/pyscancf.git). Indian Meteorological 
> Department (IMD) issues the data in separate sweeps, which is generally 
> having 10 sweeps for 10 different elevations. I tried both formats, i.e., 
> single sweep, as well as cfradial format, but I wasn't able to load it in IDV.
> Looking forward to hearing from you.

Hi Syed,

After carefully checking the uploaded files, these radar files are not CF 
complaints. The dimensions and coordinate variables are not very
well constructed, we can not build a radial coordinate system based on the 
current situation.
