Fair Use Policy for ORCHIDEE

The fair use policy is designed to ensure that the individuals and teams that develop the ORCHIDEE model receive proper credit for their work.

We first define the model code, drivers and run environment as the overall ORCHIDEE environment. Maintaining a state of the art ORCHIDEE environment come with a significant investment of time for coding, debugging and evaluating the impacts of any developments (biogeochemical, physical and anthropogenic processes) on the overall performance of the model. The fair use policy will help recognizing the intellectual contribution of the individuals who contributed to the ORCHIDEE environment.

The policy applies to the use of a referenced version described below. This model version is freely available; it is furnished by the ORCHIDEE project group who encourage its use. Please kindly inform by email (orchidee-projet at how you will use the model and of any publication plans.  The scientists who provided the ORCHIDEE environment or potentially existing model outputs will tell you if they feel they should be acknowledged or offered participation as co-authors. We assume that an agreement on such matters will be reached before publishing and/or use of the data for publication. If your work directly competes with an ongoing investigation, the scientists who provided the ORCHIDEE environment or model output may ask to have the opportunity to submit a manuscript before you submit your study with ORCHIDEE.

Recognition of intellectual contributions to the ORCHIDEE environment will be ensured by:

  • Offering co-authorship on any publication that benefits of recent improvements in the ORCHIDEE environment. We deliberately refrain from specifying ‘recent’ as it should be function of the intellectual contribution and the exposure this contribution already received.
  • Discussing, early on, intended usage of recent improvements in the ORCHIDEE environment. This discussion should prevent uses and/or applications of the ORCHIDEE environment which are in conflict with the plans of the main contributor.

The fair use policy is designed as a win-win opportunity for both users and developers of the ORCHIDEE environment. It warrants the continuation of ambitious model developments and thus contributes to safeguarding our leadership in land surface modelling.

How to use ORCHIDE

1) Free use of a referenced version

The version that was used for the CMIP5 exercice is freely available.

Access to the code:

  • downloding code: Please send an email to “orchidee-projet at” with your intended use of ORCHIDEE. You will receive the connection details to download the reference version (via svn)

Support: see the online documentation

2) Use of follow-up more recent versions

ORCHIDEE is a continuously evolving research tool. Despite the efforts of documenting and validating tags before their release, new users are likely to require help to correctly use the full functionality of ORCHIDEE and its run environment. For this purpose, we ask  new users to establish a direct contact with someone from the ORCHIDEE project group (see list of the core team) or by sending an email to orchidee-projet at with the explanation of your intended use of ORCHIDEE.

Note that we organize regular training days detailing the scientific basis of the model as well as the technical aspects of its run environment.
For new users, the first line of support is the ORCHIDEE wiki (online documentation). The second line of support is the supervisor or contact person in the core team. For users who participated in the training days and have a formal working agreement with the ORCHIDEE project team a third line of support is the help mailing list for support from unregistered users, non-academic users or users without a working agreement with someone from the “ORCHIDEE-Project team” will not be considered through by the help mailing list.

We may need your expertise

The IPSL (Institut Pierre Simon Laplace) gathers 9 laboratories whose research topics focus on the global environment with a common strategy for the study of the Earth System as a whole A major research mission is to contribute to a better understanding of the interactions between human activities in the Earth System, environment and climate dynamics at different time scales. If you have a PhD in mathematics, physics, engineering, computer science, meteorology, or physiology, or you believe that your skills could contribute to the development of ORCHIDEE as the land surface component of the IPSL Earth System model, feel free to send us your CV, a customized letter of motivation and three names of people who are willing to act as references.

Team logistics

ORCHIDEE team meetings

The ORCHIDEE project group has defined a series of regular meetings to achieve the objectives of the project group and to maintain a regular flow of information between the core “ORCHIDEE project group” and the ensemble of developers and users (non-permanent scientists and engineers). The idea is to have regular meetings each week and to alternate between:

    • Technical meetings: Restricted to the steering committee and few other active developers. These concern management of the code, scientific and technical discussions concerning the implementation of the ORCHIDEE project decisions, and follow-ups of engineering work.
    • Project meetings: Restricted to the steering committee. The main objectives are general decision making and coordination of the model developement.
    • Developer/user meeting: Open to all. The main objectives are: 1) to inform all developers/users of the code about the ongoing ORCHIDEE developments and branch integration into the main version, and 2) to present and discuss a specific ongoing development (scientific or technical).

Management of the code:

In order to increase the efficiency of the code maintenance, development and management, we have grouped the different modules and routines by processes/technical aspects, following the diagram below. For each process or technical aspect, one person from the steering committee is responsible for managing all technical and scientific problems/bugs that arise (usually managed through a “ticket” system) and to report to the steering committee about the evolution of that part of the code.

How to contact us ?

Three mailing lists are used in order to facilitate the flow of information at different levels.

    • ORCHIDEE projet ( This list is restricted to the steering committee. It may be used by external people for a general request about the ORCHIDEE project
    • ORCHIDEE DEV ( To facilitate the exchange of technical information among all users/developers of the ORCHIDEE model, in paticular to circulate information on new technical improvements/developments, to report problems/bugs and to notify about ‘commits’ made by the ORCHIDEE team. You can subscribe at
    • ORCHIDEE HELP ( For developers or users of the ORCHIDEE model to ask specific questions (mainly technical) linked to the use of the model or to report problems/bugs. This mailing list should be used only as a last resort.


Objectives of the team

The ORCHIDEE project is dedicated to the development of the global Land Surface Model (LSM) ORCHIDEE and its use for a wide range of applications (from land surface processes to climate studies). The project is centered around a project team (referred to as the “ORCHIDEE project group”) whose main objective is to coordinate the strategy for the model development, maintenance, validation, distribution, and valorisation.

The project team consists of a “steering committee” including around 15 scientists (see figure below) who meet every two months to discuss and coordinate all model developments, validation and valorisation. Three specific tasks linked to the main responsabilities of the project team have been identified with a key leader:

    • Maintenance of the ORCHIDEE code (J. Ghattas).
    • Evaluation and validation of successive code releases (N. Vuichard).
    • General code quality, including documentation, risk assessment, and promotion of the code (F. Maignan).

Project leader: Philippe Peylin

About the ORCHIDEE project team

The Orchidee project was established across several laboratories and it is dedicated to development of the global Land Surface Model (LSM) ORCHIDEE and its use for a wide range of applications from land surface processes to climate studies. The different steps of the ORCHIDEE model/project genesis are summarized in the figure below.

The genesis of ORCHIDEE

During the 1980s, the development at the Laboratoire de Météorologie Dynamique (LMD) of a global General Circulation Model (GCM) stimulated the development of a specific land surface model to calculate the energy and water balance of terrestrial ecosystems (Laval et al., 1981). In the early 1990s, the model was substantially refined with a description of the earth surface categorized into several biomes called PFTs (Plant Functional Types) which led to a version, named SECHIBA (Ducoudré et al., 1993). In the late 1990s and in the early 2000s, the Dynamic Global Vegetation Model (DGVM) ORCHIDEE (Krinner et al., 2005) was created, based on the coupling of SECHIBA with i) a carbon module, STOMATE describing the flow of carbon within the soil-plant-atmosphere continuum and ii) a dynamic vegetation module, inherited from the LPJ model, describing the evolution of natural vegetation with climate. Such effort was conducted between the LMD and LSCE laboratories.

about the ORCHIDEE project team

A team to follow and coordinate the model developements

After the mid 2000s, there has been an exponential increase in the number of users and developers in several laboratories: within IPSL (LSCE, LMD, LOCEAN), outside IPSL (SISYPHE in Paris and LGGE in Grenoble) and internationally (PKU university in China, UCLM Toledo in Spain, University of Antwerp (UA) and UGhent university in Belgium). The increase of users and associated projects was accompanied by a large number of new developments. In this context, the need to merge the new model “branches” into a common version became crucial especially to address integrated scientific questions, but it also became highly challenging. The main ORCHIDEE developers/users have thus decided to reinforce the previous organisation (carried by the IPSL) and to operate as a more structured project across laboratories. This process that started at LSCE was rapidly enlarged to the IPSL and few other national and international laboratories (listed above) with the objectives to formalize communication, developments, planning and decision making around the model. The reorganisation into a new project structure has been adapted to the size and ambitions of the group. This web site summarize the foundation of this recent organization.

Climatic impact of global-scale deforestation: radiative versus non-radiative processes

All models investigated in this study simulated a negative sensitivity for both the land and the ocean carbon cycle to future climate. However, there was still a large uncertainty on the magnitude of these sensitivities. Eight models attributed most of the changes to the land, while three attributed it to the ocean. Also, a majority of the models located the reduction of land carbon uptake in the Tropics. However, the attribution of the land sensitivity to changes in net primary productivity versus changes in respiration is still subject to debate; no consensus emerged among the models.


Europe-wide reduction in primary productivity caused by the heat and drought in 2003

This study estimates a 30 per cent reduction in gross primary productivity over Europe, which resulted in a strong anomalous net source of carbon dioxide to the atmosphere and reversed the effect of four years of net ecosystem carbon sequestration. The results suggest that productivity reduction in eastern and western Europe can be explained by rainfall deficit and extreme summer heat, respectively. The study reports that ecosystem respiration decreased together with gross primary productivity, rather than accelerating with the temperature rise.
