logo Lund-Potsdam-Jena managed Land (LPJmL)

LPJmL is a Dynamic Global Vegetation Model (DGVM) written in C, designed to simulate terrestrial natural vegetation, agriculture and hydrology at global scales. It is currently developed and maintained mainly by the Potsdam Institute for Climate Impact Research (PIK) in Potsdam, Germany.

Features

  • Dynamic Vegetation Modeling: Dynamic natural vegetation composition based on climate and underlying biophysical processes.
  • Land-Use Integration: Representation of land use such as cropping systems, managed grassland and wood plantations
  • Flexible Configuration: Highly configurable through input files and parameters.
  • Scalability: Designed for global-scale simulations, with support for parallel computation.

Getting Started

Dependencies

LPJmL is written in C and requires the following tools and libraries:

  • A standard C compiler (e.g., GCC or Clang).
  • GNU Make for build management.
  • MPI (optional, for parallel execution).
  • JSON-C library.
  • NetCDF and Udunits-2 library (optional).

For additional dependencies, refer to the INSTALL.md file.

Setup & Usage

  1. Clone the repository:

    git clone https://github.com/PIK-LPJmL/LPJmL.git
cd LPJmL

  2. Compile the source code:

     ./configure.sh
make all

For detailed setup instructions, see the INSTALL.md file. LPJmL requires additional input data to run simulations. Input files can be generated applying the Land Input Generator (LandInG) To test the model, use the provided test data:

  1. Run a test simulation:

     make test

For detailed usage instructions, refer to the documentation. For changes and bug fixes in the code refer to the changelog.

Contributing

We welcome contributions to LPJmL, including:

  • Bug fixes.
  • New model features.
  • Improvements to documentation or performance.

How to Contribute

  1. Fork the repository on GitHub.
  2. Create a feature branch: 
    git checkout -b feature-name
  3. Submit a pull request with a detailed description of your changes.

Coding Standards

Please adhere to LPJmL’s coding standards. Refer to the STYLESHEET.md for guidelines.

Support Policy

Outside of collaborative agreements with PIK:

  • No official support is provided for model setup, usage, or development.
  • Discussions on development features can be initiated via GitHub Issues.

logo Lund-Potsdam-Jena managed Land (LPJmL)
LPJmL is a Dynamic Global Vegetation Model (DGVM) written in C, designed to simulate terrestrial natural vegetation, agriculture and hydrology at global scales.
It is currently developed and maintained mainly by the Potsdam Institute for Climate Impact Research (PIK) in Potsdam, Germany.
Features
  • Dynamic Vegetation Modeling: Dynamic natural vegetation composition based on climate and underlying biophysical processes.
  • Land-Use Integration: Representation of land use such as cropping systems, managed grassland and wood plantations
  • Flexible Configuration: Highly configurable through input files and parameters.
  • Scalability: Designed for global-scale simulations, with support for parallel computation.
Getting Started
Dependencies
LPJmL is written in C and requires the following tools and libraries:
  • A standard C compiler (e.g., GCC or Clang).
  • GNU Make for build management.
  • MPI (optional, for parallel execution).
  • JSON-C library.
  • NetCDF and Udunits-2 library (optional).
For additional dependencies, refer to the INSTALL.md file.
Setup & Usage
  1. Clone the repository:
    git clone https://github.com/PIK-LPJmL/LPJmL.git
cd LPJmL
  2. Compile the source code:
     ./configure.sh
make all
For detailed setup instructions, see the INSTALL.md file.
LPJmL requires additional input data to run simulations. Input files can
be generated applying the Land Input Generator (LandInG)
To test the model, use the provided test data:
  1. Run a test simulation:
     make test
For detailed usage instructions, refer to the documentation.
For changes and bug fixes in the code refer to the changelog.
Contributing
We welcome contributions to LPJmL, including:
  • Bug fixes.
  • New model features.
  • Improvements to documentation or performance.
How to Contribute
  1. Fork the repository on GitHub.
  2. Create a feature branch:

    git checkout -b feature-name
  3. Submit a pull request with a detailed description of your changes.
Coding Standards
Please adhere to LPJmL’s coding standards. Refer to the STYLESHEET.md for guidelines.
Support Policy
Outside of collaborative agreements with PIK:
  • No official support is provided for model setup, usage, or development.
  • Discussions on development features can be initiated via GitHub Issues.
