Documentation for ORCHIDEE
Model description for Trouville 2004
This presentation (in french)
gives the structure of the model and the future releases.
Some talks (in French) about ORCHIDEE (02/10/2003)
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.
Technical note on the STOMATE & LPJ model (Krinner 99)
This technical note gives the
main
equations used by STOMATE and LPJ.
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.
