Massive-Parallel Trajectory Calculations (MPTRAC) is a Lagrangian particle dispersion model for the free troposphere and stratosphere.

Introduction

The source code of MPTRAC is available from the git repository. Please see the README.md in the git repository for introductory information. More information can be found in the user manual.

This doxygen manual contains information about the algorithms and data structures used in the code. Please refer to the ‘mptrac.h’ documentation for a first overview.
