- | 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. | + | |

- | ====Input data==== | + | |
- | A complete set of input files is provided in tar files available from the EMEP/MSC-W Open Source ftp sites: | + | |
- | [[ftp:// | + | |
- | + | ||
- | **IMPORTANT: | + | |
- | + | ||
- | The standard input files for the EMEP model are provided in two different formats, netCDF or ASCII. We presently follow as much as possible the [[http:// | + | |
- | + | ||
- | ====Model Code==== | + | |
- | The EMEP/MSC-W model code version rv4.4 is archived into a tar file available from the EMEP Open Source ftp site [[ftp:// | + | |
- | + | ||
- | The EMEP/MSC-W model is very flexible with regard to the horizontal resolution and in 2008 the EMEP domain was extended to include EECCA countries. The current version, and the provided gridded input data, have a horizontal resolution of 50x50 km2 (at 60°N) and are defined on a polar stereographic projection. | + | |
- | + | ||
- | ====Model Results==== | + | |
- | A reference run for the year 2011 have been done and the results of this run is available from the EMEP Open Source ftp site [[ftp:// | + | |
- | + | ||
- | The main output files are in netCDF ([[http:// | + | |
- | + | ||
- | =====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:// | + | |
