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.)
- Antenna Pattern Evaluation
- A 9-meter dual-offset Gregorian antenna was installed in the spring of 2008 at the CSU-CHILL radar facility to upgrade the performance from the center-fed parabolic reflector previously used at the facility. The new antenna design has several advantages over the old antenna, primarily eliminating beam blockage by using an offset-feed structure and reducing cross-polarization with a dual-reflector design. The antenna pattern was measured in the summer of 2008 by REU student Michael Wood, the results of which are presented in this article.
- Hydrometeor classification in an RHI sweep taken with the dual offset feed antenna
- Polar coordinate data processed with CSU-developed fuzzy logic particle identification software
- First Look Data Collected with the Dual Offset feed Antenna
- SOLO display program plots from selected echo situations
- Tornado Observation from May 22, 2008
- Observations by CSU-CHILL of a nearby tornado
- Examples of Polarimetric Weather Radar Applications and Limitations
- CSU-CHILL archive data examples presented during the virtual radar tour conducted for Prof. S. Yuter's (NC State University) remote sensing class on 10 April, 2008, including RHI scans through thunderstorm and snow echoes, Differential attenuation Zdr artifacts, Non-precipitation echoes (insects and smoke particles) and a Hydrometeor Classification example.
Technical Notes
These articles deal with engineering topics of interest to users of CSU-CHILL data.
- 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.
- Interpreting Housekeeping data (TN-002)
- This article discusses the housekeeping data inserted into the data stream output by the signal processor.
- Using calibration files with Time Series data (TN-001)
- This article talks about the calibration data generated by the CSU-CHILL signal processing system. When processing time series data, the calibrations must be applied to the data as shown in the article.
