Featured Articles
These are examples of CSU-CHILL data selected from meteorologically interesting cases. The data plots generally have had some basic level of post-processing applied (i.e., calculations of derived fields, utilization of specialized base maps, etc.)
- An RHI scan through a severe thunderstorm: 21 June 2010
- A single RHI sweep through a severe thunderstorm reveals several signatures in the radial velocity and dual-polarization data fields.
- Aircraft targets as seen by the CSU-CHILL radar: 16 March 2011
- High time resolution PPI sector scans were used to observe aircraft in the vicinity of Denver International Airport.
- Outflow surge from an area of thunderstorms: 8 July 2010
- A fine line marking the leading edge of low-level outflow is observed to accelerate following the rain rate peak in the parent cluster of thunderstorms.
- Example Multiple-Doppler Radar Analysis from the Colorado Front Range area: 31 Dec 2010
- Horizontal wind fields are synthesized from radial velocity data collected by the CSU-CHILL, EOL S-Pol and NWS KFTG radars in a demonstration of some of the measurement capabilities that will be available from the FRONT (Front Range Observational Network Testbed).
- Radar calibration sphere flight: 2 December 2010
- The echo returned by a balloon-borne, foil-covered sphere of known diameter is used as a calibration standard for the measurement of radar reflectivity factor.
- Local flooding in Byers, Colorado: 7 July 2010
- Two feet of water was reported to be running over the I-70 exit at Byers following the passage of several thunderstorm echo cores.
- Gust front collision: 2 July 2010
- A thunderstorm developed over Denver International Airport following a collision of two gust fronts.
- Evolution of a three body scattering signature: 26 May 2010
- An echo pattern due to three body scattering became well-defined as a severe hailstorm developed in the Commerce City area.
Technical Notes
These articles deal with engineering topics of interest to users of CSU-CHILL data.
- X-band Solid State Transmitter Monitor User's Guide (TN-008)
- User's Guide to the solid-state X-band transmitter monitor developed at CSU-CHILL.
- Clock Generator User's Guide (TN-007)
- User's Guide to the programmable clock-generator design developed at CSU-CHILL.
- Frequency Synthesizer User's Guide (TN-006)
- User's Guide to the programmable Frequency Synthesizer design developed at CSU-CHILL.
- Radar Echoes from Wind Turbines (TN-004)
- Wind Turbines have become increasingly common in recent years. Their Doppler spectral characteristics are presented, along with an animation showing the repetitive patterns present in the turbine spectra. An audio presentation of the same data is also available, clearly showing the temporal variation of the echo. A brief discussion on the effects of wind turbine proliferation on radar meteorology is also presented.
- Coherent Leakage (TN-003)
- This is a short discussion on coherent leakage, discussing the various causes of coherent leakage in weather radar receivers. Some troubleshooting tips are also provided.
