CSU-CHILL
Colorado State University–University of Chicago–Illinois State Water Survey S- and X-Band Radar

CSU-CHILL is an S- and X-band, dual-polarization scanning radar system operated by Colorado State University (CSU). It is a part of the CSU Research Facility located in Greeley, CO, but it can be transported. Simultaneous operation of the S-band (2.725 GHz) and X-band (9.41 GHz) radars allows for CSU-CHILL to provide high spatial resolution radar measurements, making it useful for hail detection. The S-band radar has a range resolution of 15-150 m and a typical range of 50-300 km. The X-band radar has a range resolution of 15-90 m and a typical range of 75-90 km. CSU-CHILL has a pulse-repetition time (PRT) of 800–2500 ms.
