- | The EMEP/MSC-W model is designed to calculate air concentrations and deposition fields for major acidifying and eutrophying pollutants, photo-oxidants and particulate matter. The present release of the model is intended to: | + | |
- | * facilitate insight in the model assumptions, | + | |
- | * encourage dialogue and collaboration with the modelling community | + | |
- | * allow individual model runs and insight on how to run different scenarios | + | |
- | + | ||
- | Questions on the EMEP model can be addressed to [[emep.mscw@met.no]]. Support to the user community will be developed here with your contribution. Please let us know what your needs for information are. | + | |

- | =====Documentation===== | + | |
- | The EMEP/MSC-W model is a chemical transport model developed at the Meteorological Synthesizing Centre - West (MSC-W) at the Norwegian Meteorological Institute (met.no). The EMEP model is a limited-area, | + | |
- | + | ||
- | * acidifying and eutrophying compounds (S, N) | + | |
- | * ground level ozone (O3) | + | |
- | * particulate matter (PM2.5, PM10). | + | |
- | + | ||
- | as well as their long-range transport and fluxes across national boundaries (Transboundary air pollution). A history of the development of the EMEP model can be found at [[http:// | + | |

- | + | ||
- | ====Computer requirements==== | + | |
- | To compile the EMEP model you need: | + | |
- | * Fortran 95 compiler | + | |
- | * NetCDF Library (> | + | |
- | * MPI Library (>1.0) | + | |
- | + | ||
- | It is necessary to compile with double precision reals (8 bytes reals). The program has | + | |
- | been used on computers ranging from a Linux laptop to supercomputers (Itanium2 cluster, | + | |
- | Intel Xeon cluster, Cray XT4, IBM power5+). It is compatible with all compilers tested | + | |
- | so far: Intel, PGI, gfortran, XL fortran. A Makefile is included, the path to netcdf (INCL | + | |
- | and LLIB) has to be adapted to your machine, and to the fortran compiler (F90) and | + | |
- | flags (F90FLAGS) to the compiler you are using. | + | |
- | + | ||
- | The code has been tested with 1 to 1024 CPUs, and scales well (for large grids). If | + | |
- | only one CPU is used 1-2 GB memory is required. If more than one, for example 64 | + | |
- | CPUs are used, 200 MB of memory per CPU is enough (in the case of a 132 X 159 grid | + | |
- | size). For runs on more than 32 CPUs, a fast interconnect is recommended (infiniband | + | |
- | for example), for smaller runs, gigabit ethernet is sufficient. It takes ~3.5 hrs on 64*Xeon | + | |
- | X5355 (2.66GHz) for a 1-year simulation. | + | |
- | + | ||
- | When downloading input data in order to do a "base run" please make sure that there | + | |
- | are 35 Gb disc space available, especially due to large meteorology input files. The model | + | |
- | can be run for shorter periods, users can download meteorology for only the period they | + | |
- | are interested in, plus one day. | + | |
- | + | ||
- | + | ||
- | =====Verification===== | + | |
- | The EMEP/MSC-W model is validated and reported to the Cooperative Programme for Monitoring and Evaluation of the Long-range Transmission for Air Pollutants in Europe ([[http:// | + | |
