HD(CP)² is the acronym for “High definition clouds and precipitation for advancing climate prediction”. This project is a BMBF funded German-wide research initiative to improve our understanding of cloud and precipitation processes and their implication for climate prediction.

The main goal of this initiative is to decrease the uncertainties in climate scenario model calculations that are based on cloud and precipitation processes. HD(CP)2 will strive to build and use a model capable of very high-resolution (100 m horizontal, 10-50 m vertical) simulations.

Figure 1 shows the region for the HD(CP)² model simulations together with key observation sites and the rain radar network used.
