CSU-CHILL radar available 
for small projects

The CSU-CHILL radar is a National Science Foundation-sponsored 
national facility maintained and operated by Colorado State University.  
The radar is an 11-centimeter-wavelength Doppler system with a peak 
power output of around 650 kilowatts.  The transmit/receive 
polarization of the radar can be switched between horizontal and 
vertical on a pulse-to-pulse basis.  Recently, the system's parabolic 
antenna was replaced with a new, state-of-the-art antenna system that 
generates a one-degree pencil beam, offers superior sidelobe 
performance, and has matched beams at horizontal and vertical 
polarizations, thereby optimizing dual polarization observations.  The 
CSU-CHILL radar measures radial velocity, reflectivity, spectral width, 
differential reflectivity, differential phase, and cross-correlation.  Data 
sets are available on Exabyte tape or nine-track tape.

CSU-CHILL support is available for small, highly focused projects 
conducted at the radar's home base in Greeley, Colorado.  These small 
projects (requiring a maximum of 20 hours of radar operational 
support) are intended to provide easy access to a state-of-the-art radar 
facility for either research or educational purposes.  Historically, such 
projects yield two to five data sets of the desired phenomena (i.e., hail 
events, snowbands, etc.).  The costs associated with the 
20-hour projects are born by the CSU-CHILL facility budget.  
Investigators interested in applying for a 
20-hour project should contact the scientific director of the facility,
