Chemical Transport Models

Model Model for Ozone and Related chemical Tracers (MOZART)
Description / Purpose 3D global chemical transport model developed at NCAR, MPI-Met and NOAA/GFDL. Comprehensive model of atmospheric composition to simulate chemical and transport processes. Includes tropospheric and stratospheric chemistry. Resolves the Earth’s chemical composition from the ground to altitude far above the highest flight cruise level, giving better perturbation signal in the upper troposphere.
Data source / Input Standard meteorological fields, anthropogenic emissions, aviation and shipping emissions.
Output Extensive chemical scheme: CO, NOx, OH, CH4, NMHCs etc in T42LR or T63LR
Spatial dimension Global
Temporal dimension Daily, monthly, annual.
Sample applications Widely used and many papers by developers and users. Currently used at MMU in 2 PhDs and work underway for publication on aircraft and shipping applications.
Model TROPOS
Description / Purpose 2D global chemical transport model that is computationally efficient. Designed to provide estimates of atmospheric composition quickly. Can be used in transient mode and useful in the investigation of NOx-related aviation impacts.
Data source / Input Standard meteorological fields, anthropogenic and aviation emissions.
Output Extensive chemical scheme including CO, NOx, OH, CH4, NMHCs etc.
Spatial dimension Global
Temporal dimension Monthly, annual.
Sample applications Developed and used at MMU for long-term integrations (100 years) and calculation of inputs to climate metric models. Basis of 1 PhD.
