The COMPASS project, in collaboration with the WorldPop project, has successfully developed and provided a new population dataset to support Earth system modeling for CMIP7 (Coupled Model Intercomparison Project Phase 7). Based on the methodology outlined in COMPASS Deliverable D3.1, this dataset has been accepted as one of the 12 official CMIP7 ‘forcing’ datasets, marking a significant contribution by COMPASS to the global climate modeling community.
The population data for the historical period is now publicly available via the ESGF input4MIPs repository, and future projections are in preparation. Full documentation is maintained alongside other CMIP forcing datasets in the input4MIPs CVs documentation.
The dataset will play a key role in simulations that feed into the IPCC’s Seventh Assessment Report (AR7), helping to represent the influence of population distribution and growth on emissions, land use, and climate interactions.
Additionally, Dr. Dominik Paprotny, Researcher at Potsdam Institute for Climate Impact Research (PIK) and member of COMPASS team, has been invited to join the CMIP Climate Forcing Task Team, contributing to the strategic coordination of CMIP7 forcing inputs. This recognition highlights COMPASS’s leadership in promoting FAIR and policy-relevant data products within the international modeling landscape.
