The domain-specific meteorological visualization tool Met.3D is an opensource effort to make interactive, 3D, feature-based, and ensemble visualization techniques accessible to the meteorological community, and at the same time to provide a framework for visualization research with application to meteorology. Since the public release of version 1.0 in 2015, Met.3D has been used in multiple visualization research projects, and has evolved into a feature-rich visual analysis tool facilitating rapid exploration of gridded atmospheric data. In this demo, we will present the current state of our efforts to contribute a new version 2 of Met.3D to the community, with extended funcionality and improved usability for meteorological users, and with a well documented implementation for extension by visualization researchers.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing->Visualization systems and toolsHuman centered computingVisualization systems and tools10.2312/evp.202511443 pages
