Please refer to these websites for more details.
- Please use the build-linux.sh script to compile the program with multi-var trajectory functionality.
- Currently, only Ubuntu 20.04 and Ubuntu 22.04 are supported by the script. To build the program on other operating systems, it is recommended to adapt the build script.
Met.3D is an open-source visualization tool for interactive, three-dimensional visualization of numerical ensemble weather predictions and similar numerical atmospheric model datasets. The tool is implemented in C++ and OpenGL-4 and runs on standard commodity hardware. It has originally been designed for weather forecasting during atmospheric research field campaigns, however, is not restricted to this application. Besides being used as a visualization tool, Met.3D is intended to serve as a framework to implement and evaluate new 3D and ensemble visualization techniques for the atmospheric sciences.
The Met.3D reference publication has been published in "Geoscientific Model Development" and is available online:
Rautenhaus, M., Kern, M., Schäfler, A., and Westermann, R.: "Three-dimensional visualization of ensemble weather forecasts -- Part 1: The visualization tool Met.3D (version 1.0)", Geosci. Model Dev., 8, 2329-2353, doi:10.5194/gmd-8-2329-2015, 2015.

Met.3D is developed at the Regional Computing Center of Universitaet Hamburg, Hamburg, Germany, and at the Computer Graphics & Visualization Group, Technische Universitaet Muenchen, Garching, Germany. We hope you find the tool useful for your work, too. Please let us know about your experiences.
Met.3D runs under Linux and Windows. Its only "special" requirement is an OpenGL-4 capable graphics card. A standard consumer (i.e. gaming) model works fine. Met.3D's current features include:
- Interactive 2D horizontal sections in a 3D context, including filled and line contours, pseudo-colour plots and wind barbs.
- Interactive 2D vertical sections in a 3D context along arbitrary waypoints, including filled and line contours.
- 3D isosurface volume renderer that supports multiple isosurfaces. Isosurfaces can be coloured according to an auxiliary variable.
- 3D direct volume rendering (DVR) with an interactive transfer function editor.
- Surface shadows and interactive vertical axes to improve spatial perception.
- Navigation for forecast initialisation and valid time and ensemble member.
- Interactive computation of ensemble statistical quantities (mean, standard deviation, probabilities, ...) of any ensemble data field.
- 3D trajectory rendering for trajectories computed internally or externally (the latter provided in NetCDF format).
- Computation of 3D streamlines and trajectories from wind fields, following computational schemes in the LAGRANTO model.
- On-the-fly gridding of ensemble trajectories into 3D probability volumes.
- Support for 3D model data that is regular in longitude and latitude in the horizontal. In the vertical, the following is supported: (a) levels of constant pressure, (b) sigma-hybrid-pressure-levels (ECMWF model), (c) any type of structured grid as long as a 3D field with pressure values is available (this can be used, e.g. for data on geometric height levels).
- Limited support for data on rotated grids (e.g., by the DWD COSMO model; data can be displayed but not overlaid with data defined on geographic lon/lat coordinates).
- Interactive ensemble Skew-T diagrams for analysis of vertical profiles.
- Data can be read from CF-compliant NetCDF files and from ECMWF GRIB files.
- A comprehensive session manager to save the current state of the program and to revert earlier visualization steps.
- Interactive visual analysis of probability volumes.
- Multithreaded data pipeline architecture.
- Modular architecture designed to allow the straightforward implementation of additional visualization/data processing/data analysis modules.

In addition to the reference publication, a second paper available online from Geoscientific Model Development describes the specific application case of forecasting warm conveyor belt situations with Met.3D:
Rautenhaus, M., Grams, C. M., Schäfler, A., and Westermann, R.: "Three-dimensional visualization of ensemble weather forecasts --Part 2: Forecasting warm conveyor belt situations for aircraft-based field campaigns", Geosci. Model Dev., 8, 2355-2377, doi:10.5194/gmd-8-2355-2015, 2015. Available at: http://www.geosci-model-dev.net/8/2355/2015/gmd-8-2355-2015.html
In addition, Met.3D has been used in a number of scientific publications. Please refer to https://met3d.wavestoweather.de/publications.html for a list.
Installation and configuration notes can be found online in the user documentation at http://met3d.readthedocs.org/.
