A Software Toolbox for Systematic Evaluation of Seismometer-Digitizer System Responses
Unique seismic datasets of extreme importance to the U.S. Air ForceÂ¿s mission to monitor underground nuclear testing may need to be discarded if the seismometer specifications, often called the Â¿response,Â¿ are unknown. However, if these unique datasets are discarded, it could diminish mission capability. This project will develop a software toolbox that will recover the seismometer response for recorded seismic data. The toolbox will include (1) a database of known seismometer and digitizer responses, (2) methods for estimating response Â¿transferÂ¿ functions between stations with and without known responses, (3) techniques for using synthetic seismograms for response validation, and (4) advanced methods for timing and polarity quality control. Commercial Applications and other Benefits as described by the awardee The toolbox would provide DOE nuclear-explosion-monitoring scientists with a valuable asset for characterizing datasets that can improve the Air ForceÂ¿s ability to detect, locate, and discriminate underground nuclear explosions. Future commercial applications would provide global and regional seismic network operators, including operators that monitor oil and gas fields, a sophisticated capability to continuously monitor the system response of their networks.
