CTBTO International Monitoring System Data for Science and the virtual Data Exploitation Centre (vDEC)
Abstract
The International Monitoring System (IMS), installed and maintained by CTBTO, is a global system of monitoring stations, composed of four complementary technologies: seismic, hydroacoustic, infrasound and radionuclide. Data from all IMS stations are collected and transmitted to the International Data Centre (IDC) in Vienna, Austria.
The main objective of acquiring the CTBTO data is to detect nuclear explosions on land, in the oceans and in the atmosphere, but the data are also extremely valuable for civilian applications like tsunami early warning and scientific studies e.g., to investigate the migration pattern and population density of marine mammals or to track radiation on a global scale. These applications return a benefit to the main purpose of detecting nuclear explosions by improving monitoring algorithms and to discriminate between explosion signals and what is considered noise from the CTBT perspective. Having many scientists collect and evaluate the data also enhances data quality. The vast amount of CTBTO data archived over almost two decades can be accessed via the virtual Data Exploitation Centre (vDEC). The vDEC contract is a zero-cost contract which contains legal requirements. vDEC provides scientists and researchers from many different disciplines and from around the globe with access to the CTBT IMS data to conduct research and to publish new findings. This poster will demonstrate examples of possible civil and scientific applications and provide an overview on geographical and technological repartition of vDEC contracts signed since 2011.- Publication:
