Welcome to Met.3D

Met.3D is an open-source visualisation tool for interactive, three-dimensional visualisation 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. Its only “special” requirement is an OpenGL 4.3 capable graphics card.


Met.3D is open-source, and available on Gitlab. The software is licensed under the GNU General Public License, Version 3.

Met.3D currently runs under Linux. 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 visualisation tool, Met.3D is intended to serve as a framework to implement and evaluate new 3D and ensemble visualisation techniques for the atmospheric sciences.


A Met.3D reference publication has been published in Geoscientific Model Development and is available online:
