Title:
Collaborative Adaptive Sensing of the Atmosphere (CASA): A New Radar System for Improving Analysis and Forecasting of Surface Weather
Conditions
Abstract:
An Engineering Research Center for the Collaborative Adaptive Sensing of the Atmosphere (CASA) was formed in the fall of 2003 by the National Science Foundation for the purpose of developing a dense network of small, low-cost, low-power radars that could collaboratively and adaptively sense the lower atmosphere (0-3 km AGL). Such a network is expected to dramatically improve sensing near the ground through a process called DCAS, distributive collaborative adaptive sensing. The CASA network is a dynamic, data-driven application system whereby the strategy for scanning will be an optimized network solution among competing end-user needs and weather constraints. Data collected from the CASA network will be assimilated in real-time for use in detection algorithms, numerical weather prediction and transportation models, and output disseminated to a wide array of end-users. Because of the distinct advantages of such a radar network, significant improvements are expected from the system in the analysis and prediction of surface weather conditions.
