Download previous MCM model input files
This archive contains ASCII files of the MCM code in FACSIMILE format.
- Users may experience some difficulties in trying to run these codes depending on the version of FACSIMILE they are using.
- The models have been tailored specifically for FACSIMILE version 3.05 (23.12.1993).
- With the later versions of FACSIMILE for windows, some changes need to be made to the code. These include specifically the command functions EXEC (now EXECUTE) and PSTREAM (now SETPSTREAM).
- Users should contact the distributors of FACSIMILE (http://www.mcpa-software.com/) in case of major difficulty, as we can not provide information on updates to the FACSIMILE program which prevent it from running FACSIMILE code written for an earlier version.
- The output files generated at present contain diagnostics and complete variable listings, and are very large. Hence, users are advised to customize these models with respect to the output that they require, and also to consider the overall time scale and time steps for the integrations which are currently set.

| PC: | MCM31boxv2.zip | |
| UNIX: | MCM31boxv2.tar.gz |
Once uncompressed, the archive contains two files.
- MCM31box.fac
- Provides a FACSIMILE deck implementing the Master Chemical Mechanism v3.1 with a basic initialisation using typical concentrations of the photochemically-labile species at the ppb or so level. These initial concentrations have no particular significance and provided solely to implement the MCMv3.1 in the simplest realistic way.
- MCM31ptm.fac
- A FACSIMILE deck with the full photochemical 5 day trajectory model for northwest Europe. Details of the model are included with the code and also described in references [Derwent et al. 1996] and [Derwent et al. 1998].
- MCM3box.fac
- Provides a FACSIMILE deck implementing the Master Chemical Mechanism v3.0 with a basic initialisation using typical concentrations of the photochemically-labile species at the ppb or so level. These initial concentrations have no particular significance and provided solely to implement the MCM v3.0 in the simplest realistic way.
- MCM3ptm.fac
- A FACSIMILE deck with the full photochemical 5 day trajectory model for northwest Europe. Details of the model are included with the code and also described in references [Derwent et al. 1996] and [Derwent et al. 1998].
- MCM2box.fac
- Provides a FACSIMILE deck implementing the Master Chemical Mechanism v2.0 with a basic initialisation using typical concentrations of the photochemically-labile species at the ppb or so level. These initial concentrations have no particular significance and provided solely to implement the MCM v2.0 in the simplest realistic way.
- MCM2cal.fac
- Provides a FACSIMILE deck with an initialisation which represents the typical conditions found in the USA. It represents the average conditions in terms of initial concentrations, emissions, boundary layer depths, temperatures and humidities from 40 EKMA OZIPR trajectory model experiments covering all the major ozone exceeding air basins. Again the run is meant to be illustrative and covers the conditions appropriate to the intense urban scale photochemical ozone formation associated with the North American continent.
- MCM2ptm.fac
- A FACSIMILE deck with the full photochemical 5 day trajectory model for northwest Europe. Details of the model are included with the code and also described in references [Derwent et al. 1996] and [Derwent et al. 1998].
