Download 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.
MCMv3.1 files have been prepared for UNIX and PC users, and stored in
compressed form.
Latest corrected versions of mcm31*.fac stored January 2010:
Some minor corrections have been made to the alpha-pinene scheme
Select from below according to your hardware type.
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].
-
MCMv3 files have been prepared for UNIX and PC users, and stored in
compressed form.
Latest corrected versions of mcm3*.fac stored May 2003:

Once uncompressed, the archive contains two files.
- 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

MCMv2.0 files have been prepared for UNIX and PC users, and stored in
compressed form.
Latest corrected versions of mcm2*.fac stored January 2001.
Select from below according to your hardware type.
Once uncompressed, the archive contains three files.
- 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].
