MAGRITTE : Model of Atmospheric Composition at Global and Regional scales using Inversion Techniques for Trace Gas Emissions

 

  • Chemical mechanism

The chemical mechanism is described in Müller, J.-F. et al.: Chemistry and deposition in the Model of Atmospheric composition at Global and Regional scales using Inversion Techniques for Trace Gas Emissions (MAGRITTE v1.0). Part A: Chemical mechanism, Geosci. Model Dev., 12, 2307-2356, https://doi.org/10.5194/gmd-2018-316, 2019.

  • Dry deposition velocity calculation

The dry deposition velocities are calculated as described in

Müller, J.-F. et al.: Chemistry and deposition in the Model of Atmospheric composition at Global and Regional scales using Inversion Techniques for Trace Gas Emissions (MAGRITTE v1.0). Part B: Dry deposition, Geosci. Model Dev. Discuss., https://doi.org/10.5194/gmd-2018-317, in review, 2018.

The code is divided in two parts :

1) The package

MOHYCAN_code.tar.gz

Last modified : 20/12/2018

 includes Fortran code and input files for calculation of stomatal resistances for H2O.

2) The package

Deposition_model_code.tar.gz

Last modified : 20/12/2018

includes Fortran code and input files for the general calculation of dry deposition velocities.

 Resolution is 0.5x0.5 degree. The user should provide meteorological fields. Typical values of those variables are assumed in the code.

The dry deposition velocity measurements used in Müller et al. (GMDD) can be found below.
