Today, a manuscript detailing the comprehensive documentation of the Python-coded VISIR-2 ship routing model has been released. VISIR-2, an open-source model, is designed to calculate least-CO2 routes in the presence of waves and currents. Additionally, it determines least-time routes for sailboats, considering both currents and leeway. This modular, Python-coded system has been validated and is Read more about VISIR-2: both preprint and source code published[…]
