Mission: To test two pairs of rotational sensors (Model R-1 and RSB-20) in Nigbor’s in-door and out-door facilities in southern California from September to November, 2006.

This task force was initiated by Willie Lee and was led by Bob Nigbor.  Two R-2 and two RSB-20 rotational sensors were ordered by the Central Weather Bureau (CWB) of Taiwan, and by the Institute of Earth Sciences (IES), Academia Sinica, Taiwan, respectively.  Kinemetrics, Inc. was awarded a contract by CWB to modify two 6-channel K2 accelerographs to record signals from these two types of rotational sensors, and turned the equipment to Bob Nigbor for testing and verification.  Willie Lee, John Evans, Chun-Chi Liu, and Chien-Fu Wu participated in this task force.  After testing, the equipment was shipped back to CWB for deployment in Taiwan by Task Force 2007-01 under the leadership of Bor-Shouh Huang <> with Chun-Chi Liu, Chien-Fu Wu, and Willie Lee as active members.
