Real-time three-dimensional radar mosaic in CASA IP1 testbed

This paper reports on a real-time three-dimensional radar mosaic technique for Collaborative and Adaptive Sensing of the Atmosphere (CASA) Integrated Project 1 (IP1) testbed. The technique exploits the dual-polarization capability of the IP1 radar network for the improvement of multi-radar composite fields. In particular, the copolar correlation and the attenuation derived from the differential propagation phase are injected to the interpolation process to derive a weighting scheme and a data quality index field for the composite fields. This technique is also served as a front-end that drives the composite reflectivity fields to the CSU DART now-casting algorithm.
