CHILL RADAR and CoCoRaHS

The CSU-CHILL National Weather Radar Facility, located in Greeley, CO, is an advanced, transportable dual-polarized dual-wavelength (S- and X-band) weather radar system. The facility is operated by Colorado State University, under the sponsorship of the National Science Foundation and the University.  They have been great supporters of CoCoRaHS for over 20 years.

 Check out Pat Kennedy's article on the important role CoCoRaHS observers can play during hailstorms.

CoCoRaHS Hail Reports Support the Analysis of Weather Radar Data Collected during a Significant Hailstorm 

"The data provided by CoCoRaHS observers is often critical in identifying the local variations of thunderstorm precipitation.  Hail production is generally confined to the more intense portions of a thunderstorm’s overall life cycle, so hail areas are often smaller features within the storm’s precipitation swath.  This makes CoCoRaHS observations especially useful in mapping hail regions.  The existence of hail can also be inferred from weather radar data.  This summary provides an example of the benefits that detailed CoCoRaHS observations can add to the interpretation of radar data collected in a damaging hailstorm."
