Some talks (in French) about ORCHIDEE (02/10/2003)
Gerhard Krinner : Global simulations with ORCHIDEE (pdf) , ppt
NicolasViovy : Validation of ORCHIDEE against fluxnet data (pdf) , ppt

A forward looking presentation of ORCHIDEE
This talk was given during the strategy meeting of the LMD held in Gurcy from the 11th to the 13th December 2000.
Description of the coding principles which guided ORCHIDEE
This presentation gives the structure in which ORCHIDEE was coded. The aim was to achieve a modular land-surface scheme which can be applied over a large range of spatial scles and which runs as well coupled as off-line. The interface to the atmosphere complies with the PILPS-4c standard and is documented on the PILPS Web pages.
A presentation given at international workshop on Technical Aspects of Future Sea-Ice-Ocean-Atmosphere-Biosphere Coupling organized by CERFACS and FUJITSU (Toulouse, 19-20 October 2000) might be of interest to understand the coupling of ORCHIDEE to the atmosphere.

Some documents which might give some guidance for using ORCHIDEE
The Input/Output of ORCHIDEE is done using the IOIPSL for which a description is available.
Some variables in the model represent complex processes and it is useful to have them clearly defined. A list of definitions is thus available. The model allows to choose from lists of variables which will be written to the history file. This is performed by choosing a history level between 0 for very few variables and 10 the most complete output list. The mechanism exists for the two componenets of ORCHIDEE : SECHIBA and STOMATE :
- The available lists of variables for the SECHIBA component
- The available lists of variables for the STOMATE componenet
A short list of publications
As ORCHIDEE is the marriage of SECHIBA and STOMATE all the older publications refer to either one of both models.
