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.
CSU-CHILL radial velocity data in a low elevation angle surveillance scan taken as a well-defined cold front approached the radar site from the northwest on 1 October 2014. Time lapse loops of the reflectivity and radial velocity data recorded during this frontal passage have been assembled.
