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 ?

Four mailing lists have been created on the IPSL server ( in order to facilitate the flow of information at different levels.


We also organize regular seminar either at LSCE or in Jussieu on land-surface related subjects. We created a specific mailing list where you can subscribe (ORCHIDEE MEETING) at:
