LPJmL - Lund-Potsdam-Jena managed Land
- 12 February 2026
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.
