At a Glance

The following patents belong to a large portfolio of technologies specifically developed through CASA, the Center for Collaborative Adaptive Sensing of the Atmosphere.

The primary objective of CASA is to improve observations and forecasting of devastating weather such as flash floods, tornados, high winds, and hail by developing new paradigms for sensing the atmosphere. These near-surface events are often missed by the current S-band national radar observation network, NEXRAD, due to the Earth’s curvature, radar beam refraction and separation between radars.

To solve the coverage problem and minimize curvature effects, CASA proposed dense networks of short-range X-band, polarimetric, Doppler radars with an adaptive scanning strategy that could sit on existing infrastructure. The first test bed, or Integrated Project 1 (IP1), was established in southwestern Oklahoma, and consists of four X-band, polarimetric, Doppler radars with overlapping coverage.

Background

CASA, the Center for Collaborative Adaptive Sensing of the Atmosphere, was established as a prestigious National Science Foundation Engineering Center in 2003 with over $40 million in federal, university, industry, and state funding. The Center brought together a multidisciplinary group of engineers, computer scientists, meteorologists, sociologists, graduate and undergraduate students, as well as industry and government partners to conduct fundamental research, develop enabling technology, and deploy prototype engineering systems based on a new paradigm: Distributed Collaborative Adaptive Sensing (DCAS) networks.

As an NSF Engineering Research Center, CASA included four academic partners: the University of Massachusetts (lead institution), the University of Oklahoma, Colorado State University, and the University of Puerto Rico. Other collaborating academic institutions were the University of Delaware, the University of Virginia, McGill University, Indiana University of Pennsylvania and University of Colorado at Colorado Springs.  Industry and government partners included: Vaisala, Raytheon, NOAA, EWR Weather Radar Systems, First RF Corporation, Paroscientific, Inc. and the National Research Institute for Earth Science and Disaster Prevention (NIED) of Japan.
