Abstract. Polyphemus is an air quality modeling platform which aims at covering the
scope and the abilities of modern air quality systems. It deals with
applications from local scale to continental scale, using two Gaussian
models and two Eulerian models. It manages passive tracers, radioactive
decay, photochemistry and aerosol dynamics. The structure of the system
includes four independent levels with data management, physical
parameterizations, numerical solvers and high-level methods such as data
assimilation. This enables sensitivity and uncertainty analysis, primarily
through multimodel approaches. On top of the models, drivers implement
advanced methods such as model coupling or data assimilation.
