LPJmL - Lund-Potsdam-Jena managed Land

Dieter Gerten

LPJmL is a global dynamic vegetation, hydrology, and carbon–nitrogen biogeochemistry model for gridded land-surface simulations (run offline or coupled to climate models). It simulates photosynthesis, stomatal conductance, surface energy balance, vegetation dynamics and competition, phenology, carbon allocation, soil organic matter turnover, and river discharge. Land use and management processes—cropland, pasture, irrigation, and harvest—are explicitly represented. Nutrient limitations and nitrogen cycling influence productivity, carbon storage, and greenhouse gas fluxes. Recent extensions include process-based methane dynamics, linking wetland and rice hydrology to vertically resolved CH₄ production, oxidation, and transport (diffusion, ebullition, and plant-mediated), yielding consistent CH₄, CO₂, N, and water budgets.

QUINCY - Quantifying the effects of interacting nutrient cycles

Sönke Zaehle

QUINCY is a state-of-the-art terrestrial biosphere model with fully coupled carbon, nitrogen, water, phosphorus and energy cycles. The objective of QUINCY is to clarify the role of the interacting terrestrial nitrogen and phosphorus cycles and their effects on terrestrial C allocation and residence times as well as terrestrial water fluxes.
