//Where graphic design meets atmospheric science//

We make use of Blender and its path-tracing engine to realistically render three-dimensional cloud fields from Large-Eddy Simulations (LES). These are not just for show, but can also be used as "instrument simulators", mimicking the way visual instruments like Total Sky Imagers (TSI) or other hemispheric cameras view the world. This allows a fair comparison between model and measurements.

More info on Blender here: [[https://blender.org|blender.org]]

Below is an gallery of rendering images of some of our LES simulations.

A few animations, including TSI movies, are posted here:
