Abstract
With the current S-band National Weather Service (NWS) Weather Surveillance Radar — 1988 Doppler (WSR-88DP) network, we can not observe the lower troposphere, where many hazardous weather events occur, due to the effect of Earth's curvature. In order to overcome the fundamental coverage limitations of WSR-88DP network, the National Science Foundation Engineering Research Center (NSF-ERC) for Collaborative Adaptive Sensing of the Atmosphere (CASA) has proposed a new weather sensing paradigm by deploying dense network of shorter-range, low-power X-band dual-polarization radars. The topology of CASA network allows for high-resolution observations of the first 2 km of the troposphere and also provides large areas of overlapping coverage, which is ideal for dual- and multi-Doppler retrievals. The high spatial-temporal-resolution observations and multi-disciplinary research during the Integrative Project 1 (IP1) test bed has demonstrated the viability of CASA concept.
