Polyphemus: Air quality modeling system

http://cerea.enpc.fr/polyphemus

Polyphemus is a Cyclops in Odyssey  whose name roughly means "multiple speeches". It is consistent with the goals of the system, that is, gathering on the same platform:

• several models: with Gaussian, Eulerian, Lagrangian ... formulations;
• several scales: from small/local scale to continental scale;
• multiple polluants: passive, radionuclides, photochemistry, aerosols, ...
• processing from many inputs (meteorological models, ground data);
• many advanced methods: data assimilation, ensemble forecasting, models coupling, ...

It is written as much as possible with modern computer languages (mainly C++), and only perennial and scalable developments are included. Polyphemus is open. It is open source, distributed under GNU GPL, well documented (for users and developers), and released on a regular basis. Open also means that contributions from other teams are welcome.

In this version, Polair3D chemistry-transport-model is coupled with SSH-aerosol v1.3 to simulate the particles.
