ctraj is a Lagrangian transport library written in C++. It includes two-dimensional codes for basic atmospheric trajectory integration, semi-Lagrangian tracer simulation, and contour advection. It also includes a novel dynamical tracer reconstruction method called PC proxy.
Release Notes: Three main algorithms (trajectory integration, tracer simulation, and contour advection) have been completely refactored. They are more general and extensible, support analytic wind fields, and have easier importation of gridded wind fields from other sources, including ECMWF.
