Met.3D -- a tool for interactive 3D visualization of meteorological ensemble simulations

2.3.2016, 14:15: Dr. Marc Rautenhaus, TU München

Weather and climate predictions require meteorologists and atmospheric scientists to explore large amounts of simulation data, and to assess the uncertainty of the predictions. Visualization methods that facilitate fast and intuitive exploration of the data hence are of particular importance.

In this talk, I introduce our work on "Met.3D", a new open-source tool for the interactive 3D visualization of atmospheric ensemble predictions. The tool has been developed with the primary motivation to support weather forecasting during aircraft-based atmospheric field campaigns at the German Aerospace Centre (DLR), however, is applicable to further forecasting, research and teaching activities. For example, we are interested in exploring its value for climate research.

We address the issue of spatial perception in the 3D view and present approaches to using the ensemble to allow the user to assess simulation uncertainty. Met.3D uses modern graphics technology to achieve interactive visualization on standard consumer hardware.

In this talk, I will show examples of visualizing forecast data from the European Centre for Medium Range Weather Forecasts (ECMWF) and discuss our ongoing work on ensemble visualization for atmospheric data.
