Uncertainty quantification of atmospheric transport and dispersion backtracking using an ensemble approach

Atmospheric transport and dispersion backtracking is important for the verification regime of the Comprehensive Nuclear Test-Ban-Treaty, which bans nuclear explosions worldwide. Knowledge of the uncertainty on atmospheric transport and dispersion backtracking gives more confidence in the analysis of nuclear test explosion signals picked-up by the International Monitoring System (IMS). Here we present an ensemble approach to quantify uncertainty and apply the technique on recent radioxenon measurements taken by the IMS.
