Providing Data for Nuclear Explosion Monitoring – WFNE Repository

Usage of a high-quality data set is a key element for any geophysical analysis. The Waveforms From Nuclear Explosion (WFNE) is a comprehensive repository providing access to a large volume of information of potential interest to the nuclear explosion monitoring community. It was developed and is maintained by Leidos under sponsorship of the Defense Threat Reduction Agency (DTRA). WFNE provides convenient access to source parametric data (origin, bulletin and other geophysical parameters) on all the 2,157 atmospheric, underground and underwater nuclear explosions detonated in the world between 1945 and 2017, and to their associated waveforms and station/instrument information, as collected from many sources. Distance domain for waveforms ranges from local to teleseismic (0.8-179 degrees). Detailed presentations of the test sites and detonations in each test site are provided as “Event Summaries”, including main results of studies and references.

WFNE is built as a trusted data set, starting from the previous data repository “Nuclear Explosion Database (NEDB)” that was accessed in the past by numerous users in the U.S. and international nuclear explosion monitoring community. Added information consists in a large volume of seismic, hydroacoustic and infrasound data collected from a variety of data sources, including the results of recent efforts on rescue of pre-digital seismic data via digitization. All data are collected from open sources; they are checked for completeness and quality and converted into a consistent format before being merged into WFNE, offering easy access to a correct and well-organized data set, ready to be used as input for research studies. Over 100,000 waveforms ranging from digitized analog recordings for the oldest explosions to recent International Monitoring System (IMS) data are included in WFNE. Data continues to be collected from newly identified sources. Using web-based access, users can search, visualize, and download data of interest for their own research.
