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

Role & responsabilities of the team
The ORCHIDEE project group:
Makes decisions about
-
- the developments that will integrate into the standard version of ORCHIDEE
- the order in which these developments will be included
Coordinates:
-
- Recruitment of engineers dedicated to model developments
- Planning of the different engineers resources
- Shared funding to hire some of the engineers
-
- Interactions with the different laboratories and institutes that are involved in the
development of the model, and in particular the “pôle de modélisation” of IPSL institute.
- Interactions with the different laboratories and institutes that are involved in the
Guarantees:
-
- Regular deliveries of tagged versions of the model and their robustness at several computer centers (CCRT, IDRIS, LSCE)
- Scientific evaluation
- Updates of code documentation within these tagged versions
- Production, archiving and access to reference simulations (both uncoupled and coupled to the GCM)
- Training to new users through regular courses
- User support through several tools (wiki site, help list via email, etc)
Communicates to all partners (developers, users, partner institutes) information on :
-
- developement planning and their integration into the main code
- ongoing and forthcoming research projects that use ORCHIDEE
- mid-term strategy plans by annually updating this document.
Organises:
-
- an annual general assembly
-
- a project review with the partner institute managements
(LMD and LSCE laboratories, “pôle de modélisation” of IPSL)
- a project review with the partner institute managements
