Description#
Massive-Parallel Trajectory Calculations (MPTRAC) is a La-grangian particle dispersion model for the analysis of atmospheric transport processes in the free troposphere and stratosphere.
MPTRAC calculates air parcel trajectories by solving the kinematic equation of motion using given horizontal wind and vertical velocity fields from global reanalyses or forecasts.
Mesoscale diffusion and subgrid-scale wind fluctuations are simulated using the Langevin equation to add stochastic perturbations to the trajectories. A new interparcel exchange module represents mixing of air.
Additional modules are implemented to simulate convection, sedimentation, exponential decay, gas and aqueous phase chemistry, and wet and dry deposition.
Meteorological data pre-processing code provides estimates of the boundary layer, convective available potential energy, geopotential heights, potential vorticity, and tropopause data.
Various output methods for particle, grid, ensemble, profile, sample, and station data. Gnuplot and ParaView interfaces for visualization.
MPI-OpenMP-OpenACC hybrid parallelization and distinct code optimizations for efficient use from single workstations to HPC and GPU systems.
The model has already successfully completed a sprint as part of the natESM project. Findings and solutions from the sprint can be found in the documentation.
