    2007

    2006

  • 21/02/2006 [Isotopes de la cellulose et Hydrologie Tristan d'Orgeval] 2 réunions se sont succédées de jour là:
    1. la première, organisée par Valérie Masson, portait sur les mesures faites par son équipe sur les isotopes de la cellulose dans les cernes d'arbres. L'objectif étant de définir les éventuelles études que nous pourrions réaliser conjointement (groupe ORCHIDEE-équipe de Valérie);
    2. la deuxième réunion avait pour objectif de faire le point sur les travaux récents menés par Tristan d'Orgeval, Patricia de Rosnay et Martial Mancip sur la mise au point de la nouvelle version de l'hydrologie dans ORCHIDEE.
  • 16/01/2006 [Chimie ORCHIDEE] L'objectif de cette réunion était de préparer l'inclusion définitive des émissions de composés biogéniques dans ORCHIDEE. Ces émissions ont été introduites par Juliette Lathière pendant sa thèse.

    • 2005

  • 20/09/2005 [Nouveau site Web d'ORCHIDEE] L'objectif de cette réunion était de faire le point sur le stage de Vincent Kiatkowski qui a travaillé sur la nouvelle version du site Web d'ORCHIDEE lors de son stage d'ingénieur avec Martial Mancip.
  • 22/06/2005 [Projets soumis à l'ANR] L'objectif de cette réunion était de présenter les différents projets ayant été soumis à l'ANR, impliquant ORCHIDEE. Il était important
    1. de faire circuler l'information sur les travaux envisagés autour de l'utilisation et des développements du code,
    2. d'évaluer les éventuelles implications de Martial pour une aide à ces développements,
    3. de sensibiliser les personnels impliqués aux versions de modèle disponibles, et de les encourager à travailler sur des versions comparables dans la mesure du possible.
  • 17/05/2005 [ORCHIDEE et les differents projets d'assimilation et d'inversion] L'objectif de cette réunion était de faire le point sur
    1. les projets d'optimisation de paramètres du modèle (en cours),
    3. d'assimilation de données dans ORCHIDEE (à venir), et de préparer le travail du développement de l'adjoint du modèle qui démarre au LSCE (travail Franois Delage en CDD).
  • 12/04/2005 [ORCHIDEE et l'utilisation des sols] L'objectif de cette réunion était de faire le point sur les travaux menés autour du land-use dans ORCHIDEE à l'IPSL. Nous n'avons pas pu faire le tour de ces différents travaux qui feront donc l'objet d'une autre réunion avant la fin de l'année 2005 puisque l'essentiel des discussions a tourné autour de la définition de cartes et des scénarios que nous envisagions d'utiliser.
  • 08/03/2005 [Effets du passage de l'hydrologie standard à l'hydrologie multi-couches] L'objectif de cette réunion était de discuter des effets du passage de l'hydrologie standard (Ducoudré et al. 1993, de Rosnay et Polcher 1998) à l'hydrologie multi-couches (de Rosnay et al. 2000) sur les flux et bilans simulés par ORCHIDEE. Le calcul des stress hydriques influenant le carbone n'ont pas été revus ni vérifiés, il s'agissait donc également de discuter de la formulation de ces stress.
  • 08/02/2005 [Présentation de Martial Mancip. Discussion sur les premières étapes de son travail.] L'objectif de cette première réunion de l'année 2005 était de présenter Martial Mancip à l'ensemble du groupe, et de discuter des priorités de son cahier des charges.
