During the peer-review of the latest manuscript regarding the VISIR model ( it became apparent that a cartographic projection was missing.‍. This oversight impacted ship course calculations . The bug has been addressed by releasing a new version of VISIR-2 (Python) and applying a patch to VISIR-1 (Matlab). It is strongly recommended to download the Read more about IMPORTANT NOTICE TO ALL VISIR USERS[…]

VISIR-2: both preprint and source code published

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[…]

VISIR-2 routes on the EMOD-PACE map viewer

The EMOD-PACE (EMODnet PArtnership for China and Europe) project now displays VISIR-2 routes on its map viewer. Least-CO2 routes of a 800 TEU feeder (a small container ship) calling at Singapore and other harbours along the maritime silk road can be explored via the viewer. The routes were computed for several months and departures dates Read more about VISIR-2 routes on the EMOD-PACE map viewer[…]

GUTTA-VISIR presented at international workshop

The GUTTA-VISIR system (here a video-tutorial) was presented by Gianandrea Mannarini in the frame of the “decarbonisation” session of the “Journey of a droplet to the ocean of decarbonisation” workshop, chaired by the journalist Marina Lalovic. The presentation regarded the functioning of the system, devised for computing least-CO2 ferry routes from wave and current forecasting Read more about GUTTA-VISIR presented at international workshop[…]

GUTTA-VISIR released in beta

The beta version of a service for operational ship routing for ferries in the Adriatic Sea was released on Oct.8, 2021. The service, called GUTTA-VISIR, allows the user to browse CO2-optimal routes, taking into account wave and sea current forecasts. GUTTA-VISIR enables discovery of optimal routes with several departure dates and times, and even for Read more about GUTTA-VISIR released in beta[…]

VISIR model source code on Zenodo

The source code of VISIR-1.b (Mannarini & Carelli, Geosci. Model Dev., 2019) can also be downloaded¬† from Zenodo. The VISIR release published on Zenodo is identical to the one on and includes all files and documentation necessary for running the simulations shown in the paper and preparing the figures. Should you experience any troubles Read more about VISIR model source code on Zenodo[…]

VISIR-1.b: peer-reviewed paper and source code published

A new milestone in VISIR development is now achieved: following last February’s publication of the model source code on Zenodo, a peer-reviewed paper describing the new model version 1.b has been published this week on the Geoscientific Model Development journal. The paper includes derivation of the equations for vessel advection from ocean currents, validation of Read more about VISIR-1.b: peer-reviewed paper and source code published[…]
