Training sessions

These practical sessions were used during a training day in Paris (27 March 2007). They should help learning Polyphemus, after the system is installed and the test case(s) is/are done. They cover several important applications of Polyphemus.

For each session, you will find its text (explanations and instructions) and an archive (data and configuration files). Each archive expands itself in polyphemus-sessions/[name of the session]/. Hence you may expand the archives of several sessions at the same location; they will all appear in polyphemus-sessions/.

All sessions require that you install Polyphemus-[version] in polyphemus-sessions/Polyphemus-[version]/, where [version] stands for the version number of the Polyphemus you have installed.

NB: Have a look at the bottom of this page as indications are given about where to find the necessary raw data to your simulations.

Where to find the necessary data?

Here are the links to the data necessary which have not been included in the archives :

• GLCF classification, necessary for the first session on radionuclides and the first session on aerosol.
• USGS land use classification for Europe for the first session on aerosol.
• USGS land use classification for Africa for the first session on aerosol.
• the meteorological raw data, necessary for the first session on aerosol.
• gap-filled emissions from EMEP for year 2004, all countries, all activity sectors, as "Grid 50 km x 50 km, Semicolon separated", for CO, NH3, NMVOC, NOx, SOx, PM2.5, PMcoarse. It is necessary for the first session on aerosol.
