Lund-Potsdam-Jena Dynamic Global Model (LPJ)
|
|
Description
|
The LPJ model combines process-based, large-scale representations of terrestrial vegetation
dynamics and land-atmosphere carbon and water exchanges in a modular framework. Features include
feedback through canopy conductance between photosynthesis and transpiration, and interactive
coupling between these “fast” processes and other ecosystem processes, including
resource competition, tissue turnover, population dynamics, soil organic matter and litter
dynamics, and fire disturbance.
|
|
Appropriate Use
|
Photosynthesis, evapotranspiration, and soil-water dynamics are modeled on a daily time step, and
vegetation structure and PFT population densities are updated annually.
|
|
Scope
|
Global at 0.5° latitude and longitude resolution.
|
|
Key Output
|
Vegetation structure, biomass carbon.
|
|
Key Input
|
Latitude, longitude, climate, soil texture, CO2.

Applications
|
Being applied in many different contexts, LPJ has been able to show multiple aspects of biospheric
vulnerability to climate and land use change, as well as the feedbacks that will likely arise from
broad-scale alteration of the land surface.
