JRODOS Multi-Model Atmospheric Dispersion Pipeline for Nuclear Emergency Planning

The tool supports ensemble-based analysis of cell-wise simulation results by transforming binary model outputs into geospatial products suitable for inter-model comparison and publication-quality reporting. Its main workflows include probabilistic exceedance mapping, signed relative-frequency comparison between two Atmospheric Dispersion Models (ADMs), categorical overlay analysis among three ADMs, and threshold-based overlay analysis for identifying robust regions of probabilistic agreement.

The framework reads scenario-specific binary result files, extracts one scalar value per computational grid cell and ensemble run, computes statistical indicators such as exceedance probability or relative activation frequency, joins the derived quantities to a geospatial computational grid, and renders classified map outputs. The architecture separates configuration handling, path resolution, data loading, geospatial joining, statistical computation, plotting, and pipeline orchestration into dedicated modules.
