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 reflectivity data in a low elevation angle PPI scan through a thunderstorm complex on 27 August 2014. The horizontal wind field at the 2.4 km MSL height level in the storm, and in the ambient environment ahead of the precipitation system, has been synthesized using dual-Doppler techniques.
CSU-CHILL RHI scan through an area of thunderstorms on 27 June 2014. Arrow sketched onto the radial velocity (lower) panel shows the general transport of surface-level air up to tropopause heights by the vertical motions in the convective echo system.
