The Nars array
Abstract
We present a detailed description of the instrumentation and design of the Network of Autonomously Registrating Stations (NARS). The instrumentation of each station consists of three Teledyne Geotech SL 210/220 long period seismometers and a Kinemetrics PDR-2 digital event recorder. This off-the-shelf technology was supplemented by specially designed pre-amplifiers, response shaping tilters and time receivers which calibrate the PDR-2 clock in an automatic fashion. Expressions for the full system response are derived. and station locations are given.Authors contributing to Netherlands Journal of Geosciences retain copyright of their work, with first publication rights granted to the Netherlands
