Welcome to MPTRAC!

Massive-Parallel Trajectory Calculations (MPTRAC) is a Lagrangian particle dispersion model for the analysis of atmospheric transport processes in the free troposphere and stratosphere.

Features

These are some of the most important features of the MPTRAC model:

  • MPTRAC calculates air parcel trajectories by solving the kinematic equation of motion using given horizontal wind and vertical velocity fields.

  • Mesoscale diffusion and sub-grid scale wind fluctuations are simulated using the Langevin equation to add stochastic perturbations to the trajectories.

  • Additional modules are implemented to simulate convection, sedimentation, exponential decay, gas and aqueous phase chemistry, wet and dry deposition.

  • Meteo data pre-processing code to calculate boundary layer, convective available potential energy, geopotential heights, potential vorticity, and tropopause data.

  • Various output methods for particle, ensemble, gridded, sample, and station data. Gnuplot interface for direct visualization.

  • MPI-OpenMP-OpenACC hybrid parallelization for efficient use from single workstations to HPC and GPU systems.

  • Distributed open source under the terms and conditions of the GNU GPL.
