Infrastructure
MERGE researchers are active in using research infrastructure, some of which are partly financed by MERGE.
Some examples of the research infrastructure that is available to our researchers are listed below.
LPJ-GUESS (Lund-Potsdam-Jena General Ecosystem Simulator)
LPJ-GUESS is a process-based dynamic vegetation-terrestrial ecosystem model designed for regional or global studies. Models of this kind are commonly known as dynamic global vegetation models (DGVMs). Given data on regional climate conditions and atmospheric carbon dioxide concentrations, it can predict structural, compositional and functional properties of the native ecosystems of major climate zones of the Earth.
Researchers and users of LPJ-GUESS can explore a wide range of ecosystem properties, such as vegetation cover (by plant functional types or major species), biomass and soil organic matter carbon pools, leaf area index (LAI), net primary production (NPP), and carbon fluxes, including emissions from wildfires and biogenic volatile organic compounds (BVOCs). The model also simulates hydrological and nutrient processes like evapotranspiration, runoff, and nitrogen cycling.
The latest version (4.1) introduces expanded capabilities, including methane emissions, soil nitrogen chemistry, permafrost dynamics, and an updated wildfire model, making it even more versatile for studying climate-ecosystem interactions.
LPJ-GUESS, short for Lund-Potsdam-Jena General Ecosystem Simulator, was initially developed by Ben Smith at Lund University in collaboration with the Potsdam Institute for Climate Impact Research and the Max Planck Institute for Biogeochemistry. Over time, researchers from institutions worldwide have contributed to its ongoing development and refinement.
LPJ-GUESS is openly available for research and applications in ecology, climate science, and environmental modeling. Users from diverse backgrounds are encouraged to explore its capabilities and contribute to its continuous improvement.

DataGURU
DataGURU is a tool for researchers to disseminate and find data on climate, land use, biodiversity and related areas.
The tool can also be of value as open data strategy in future applications for research funding. You can share your data with DataGURU – and make sure that your research makes even further use and gets more citations. Regardless of where you put your data, it is easy to tell DataGURU where it is and make it available to DataGURU users.
This work has been commissioned by the strategic research areas BECC and MERGE.
