MOHID Lagragian is a comprehensive high-performance Lagrangian tracer model, with sources, sinks, particle types and several options for forcing and I/O. Altough mainly developed for oceanographic and fluvial contexts, application to atmospheric and other planetary settings should be trivial.
Available functionalities are
- Robust pre-processing, modelling and post-processing tools
- Support for netcdf-cf files with currents, winds and wave fields, as well as water quality (salinity, temperature)
- Ability to model passive, bouyant and degrading tracers
- Stokes drift, windage, beaching, resuspension and turbulent diffusion models and options
- Ability to model millions of tracers in a modest laptop machine
- Simple and fully documented simulation set-up files, ready to be abstracted by a UI
- Raw vtk time encoded output, directly compatible with Paraview and other standard post-processors and renderers
- Flexible python post processor, using cross-simulation reuseable post-processing recipes, ready to be automated
- Computation of volumetric averages and cumulative integrations, exporting the results to standard netcfd files, so you can explore the results using GIS software or publish to a thredds server
- Production of high-quality mapped plots and shapefiles using matplotlib and pandas, allowing for arbitrary calendar, integration types, subdomains including polygons and plot type combinations
- Documentation on instalation, code structure, case preparation, post processing and general useage. Fully self contained examples to get you started
- Pre-built windows executable
- Cross-platform compliant, tested and deployed
- Cmake based project, easy to set up for local compilation if required
