Preliminary analysis of the Vaisala TLS-200 network deployed during the CHUVA campaign in Brazil

As part of the CHUVA campaign in and around Sao Paulo, Brazil, in January - March 2012, Vaisala installed and operated a network of five of its new TLS-200 sensors. Each sensor includes both an LF component that measures the arrival times and angles and a VHF interferometer component that measures the arrival angles of VHF emissions primarily from cloud discharges. In this report, we present a preliminary analysis of the detection capability of the TLS-200 network, with a focus on cloud discharge detection and classification.
