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.

Mesocyclone radial velocity pattern (circled) at a range of ~15 km from the NWS KFTG radar on 20 July 2013. The narrow (0.3 deg) beamwidth of the CSU-CHILL X-band (9 GHZ) channel allowed the collection of high resolution data from this same circulation despite its being at a range of ~80 km. Various data plots, including a dual-Doppler horizontal wind field synthesis, have been prepared. more
