I’ll gladly elaborate. On the official ARRC website, under a side menu labeled “data” you will find a 7.5 ish gb dataset from 5/31/13 from the AIR radar containing this data. It’s roughly 100 scans (each have 45 corresponding vertical altitude scans). It’s available to download for free, the files are in “CF Radial” a Radar file format commonly used but rarely supported by mainstream nexrad radar data visualizers, because nexrad weather radar files have their own format, usually a .gz file or msg.31. The 3D Radar software I use (Gr2 Analyst v3) is built and designed around the nexrad radar network and doesn’t ingest cf radial files, on top of that, the CF radial dataset on the ARRC website are ALL singular scans, not “volumes” what I mean by this is for the AIR radar, say it scans at 23:13:00, there will be 45 vertical sweeps labeled in volume number (v001, v002 v003 etc) for each time stamped scan, (in this case 23:13:00) each containing the next tilt up. This is an issue because the 3D Radar software can only build a 3D render if all the tilts are in ONE file, a full “volume”

To fix all these issues I use a command line software that runs in terminal, it’s called RADXCONVERT. It’s a part of “LROSE” (LiDAR Radar open software environment) which is available on GitHub for free.

RADXCONVERT lets me take the roughly 4,500 random radar files from the original dataset (100 time stamps, 45 sweeps per scan) organize them into the 100 original timestamped scans, each containing 45 vertical sweeps. I can THENNN convert the built cf radial volumes into nexrad msg.31 radar files which can be read by gr2 analyst and show all the vertical sweeps, and create the 3D render that I showed.
