| VCHILL users note: The latest version of Java (release 7 update 51) enforces stricter rules regarding self-signed certificates. Consequently, VCHILL will not run under Java 7u51. While we are working to resolve this issue, we suggest that you use Java 7 update 45 and change your java settings to allow a self-signed java app to run after a warning is given. For more information on how to do this, please see this CSU page which provides instructions for changing your Java version etc.

CSU-CHILL S-band (3 GHZ) data collected in a 0.5 degree elevation angle PPI scan of a thunderstorm on 27 July 2013. Differential reflectivity (Zdr) is reduced to near 0 dB in the echo core due to the presence of hailstones. Time lapse animations of the development of this hail signature have been prepared.

Layered air flow
CSU-CHILL S-band radial velocity data in an RHI scan on azimuth 015 degrees. Inbound (negative in sign) velocities maximize within the surface-based, post cold frontal airmass. Above 2 km AGL, the direction of the synoptic flow varies with height in a way that causes the radial velocity observed in the RHI plane to have layers with both positive and negative signs. (Both away from and towards the radar motion components.)
