HD(CP)² is a BMBF funded German-wide research initiative to improve our understanding of cloud and precipitation processes and their implications for climate prediction.

Already working in its second phase (April 17 – March 19), the project now addresses the cloud precipitation problem by a number of [scientific questions] related to cloud formation. It utilizes the ICON-LEM (ICOsahedral Non-hydrostatic Large Eddy Model) that provides an previously unknown horizontal resolution of 156m. High-resolution simulations are performed over very diverse regions, such as Germany and the Tropical Atlantic.

The first funding period of HD(CP)² focused on the optimization of the ICON model for Large-Eddy simulations and on the improvement of ground, in situ and satellite based observations of cloud and precipitation events.
