QUINCY is a state-of-the-art terrestrial biosphere model with fully coupled carbon, nitrogen, water, phosphorus and energy cycles and was developed at the Max Planck Institute for Biogeochemistry in Jena. Different aspects of the model are further developed at different groups/institutions within third-party funded projects such as the ESM2025, RESMON and FOREXD.
It is following the structure and modularization of ICON-Land, where it is fully integrated as an alternative to the land surface scheme JSBACH4.
The full QUINCY model provides a CANOPY mode (biogeophysical processes (radiation, hydrology, canopy resistance etc.) , a PLANT mode (vegetation biogeochemistry and dynamics processes) and a stand-alone SOIL mode (soil biogeochemical scheme). And for future scientific developments an alternative, advanced, microbially soil beogeochemical model (Jena Soil Model JSM).
The software is currently restricted (GPLv3) [access limited to BGC employers and guests], but is planned to be open-source (BSD-3C license) - we will keep you updated.
