Modelling Strategy of RD1

Maintenance and development of RD1’s models have been central to RD1’s ability to deliver science. Four major strands of modelling can be distinguished:


Developing a next-generation comprehensive Earth system model (Potsdam Earth Model POEM, phase 1) while continuing operations of its precursor model (CLIMBER-3α).


Developing a new Earth system model of intermediate complexity CLIMBER-X for time scales up to hundreds of millennia, which will replace the earlier CLIMBER-2 model.


Developing key component models employed for POEM and stand-alone applications, particularly the global land biosphere model LPJmL (LPJmL3 comprehensively updated to LPJmL4 and expanded to LPJmL5) and the ice dynamics model PISM-PIK.


Eventually integrating selected (often highly non-linear) effects of social macro-dynamics (e.g. of preference dynamics) into Earth’s biogeochemical cycles (copan:CORE model, in collaboration with RD4 and the GaNe FutureLab).
