Colorado State University - CHicago ILLinois radar, colloquially CSU-CHILL, is a semi-mobile, dual-frequency weather surveillance radar developed in 1970 by the University of Chicago and the Illinois State Water Survey, which has since been moved to Colorado on behalf of Colorado State University.[1]
Description
CSU-CHILL is used to study atmospheric principles and precipitation on a small scale with the use of two frequencies. It has a transmitter consisting of both S and X-bands, both using a klystron. Each transmitter can individually transmit its respective frequency through its own feed horn onto the 9m offset parabolic antenna. Moreover, this configuration aids in the ability to gather samples from various polarizations. Thanks to this, the type of precipitation can be easily discerned.[2] CSU-CHILL is protected by a pneumatic dome and is within proximity of its control buildings.[3] It is often positioned near Greeley, Colorado, but is semi-mobile. It is movable in separate pieces, and can be quickly assembled or dissembled to participate in a field study. [4]
