In early January 2025, we organized a workshop to bring together the parallel developments in land surface modelling to reach the scientific objectives of the CALIPSO project & ensure we can make a long-lasting impact on the Earth System Modelling community. The aim of CALIPSO is to increase accuracy of predicting carbon losses from vegetation and soils, and associated feedbacks with the climate systems.
During two days, we discussed the progress during the first 1.5 years of the project and revisited and refined the model development plans around the land surface model ORCHIDEE and the IPSL Earth System Model for the upcoming years. Members of all 4 challenges of CALIPSO were joined by Philippe Peylin (LSCE, Paris) and Laurent Bopp (ENS, Paris) in their functions as coordinators of the ORCHIDEE and IPSL-ESM developer teams for CMIP7.
The meeting took place in Chantilly North of Paris. The nearby mixed forests experience die-back of oak trees over the last decade which puzzles the forest managers, which reminds of the urgency to improve our understanding of carbon loss pathways and the underlying processes.
