Real-time implementation of the network-based reflectivity retrieval for CASA

The first generation testbed of the Center for Collaborative Adaptive Sensing of the Atmosphere (CASA-IP1) is currently operational in Oklahoma. The CASA-IP1 system is a radar network observing a weather event simultaneously by four radars. Within the CASA, a network-based reflectivity retrieval technique has been developed and evaluated extensively. This paper presents the evaluation of the network-based reflectivity retrieval by comparing retrieval results using CASA-IP1 data with WSR-88D observations. This paper also describes the design and implementation of an architectural framework for real-time processing of the network-based retrieval algorithm. Experimental results show that the implementation meets the real-time requirement of CASA.
