The Nuclear Explosion Database (NEDB ):A New Database and Web Site for Accessing Nuclear Explosion Source Information and Waveforms

摘要

The Nuclear Explosion Database (NEDB) project has provided access to source parameter data and associated waveforms for worldwide nuclear explosions, as documented in a series of reports (e.g., Yang et al. 2000). These NEDB data are available online at http://www.rdss.info/(access currently restricted to authorized users pending open release of all data). As described in Bahavar et al. (2007), access to the data has recently been upgraded; and, in some cases, events have been added or the associated source parameters have been refined utilizing new information sources (e.g., Department of Energy—DOE 2000; Springer et al. 2002; Khalturin et al. 2005; Bennett et al. 2006; Defense Threat Reduction Agency—DTRA 2008;Kim and Richards 2007). In addition to performing a range of QA/QC checks on the source data (e.g., comparisons with satellite imagery), station calibration and response information have been improved to make archived waveform data from the NEDB more useful to the research community. More specifically,an analyst-reviewed digital waveform archive, consisting of over 120,000 nuclear explosion recordings, has been implemented for online access.
