National Weather Radar Facility
The CSU-CHILL National Weather Radar Facility, located in Greeley, CO, is an advanced, transportable dual-polarized S-band weather radar system. The facility is operated by Colorado State University, under the sponsorship of the National Science Foundation and the University.
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.

Various data plots, including a dual-Doppler horizontal wind field synthesis, have been prepared. more
