- | Clouds in the Arctic appear in many forms. Much is still not understood about their behavior, which is for a large part due to the difficulty in sampling such clouds at high latitudes. At InScAPE we use dedicated large-eddy simulation based on available measurements to study such clouds in a virtual laboratory setting. Among others, we use data from recent field campaigns, including two recent cruises by the Polarstern Research Vessel (RV). The first is the PASCAL campaign north of Svalbard in 2017, and the other is the year-long MOSAiC drift in 2019-2020. | + | Clouds in the Arctic appear in many forms.

At InScAPE we explore new pathways to investigate and detect cloud field morphology and to capture this in conceptual models. An exciting new effort is to use the Blender ray tracing tool for scientific renderings of simulated clouds fields. |
