Short summary
We introduce a Lagrangian atmospheric transport model (AgPaDS) that complements existing approaches by providing an efficient massively parallelized implementation and a unique option for advanced live 3-D visualization of simulation data on global scales for supporting exploratory analyses. The tool is tailored to applications in crop epidemiology and can be used to improve assessment of risks posed to food production by windborne crop disease epidemics.
