Colleagues : Polcher, Cheruy, Hourdin (LMD), Guimberteau, Campoy, Magand (Sisyphe), Ciais, de Noblet, Ottlé (LSCE)
- Primary objective of your current work with ORCHIDEE: I supervise developments and validation exercises on the hydrological aspects of ORCHIDEE, including the interactions with the boundary layer.
I use the two versions ORCHIDEE-Choisnel and ORCHIDEE-Richards.
- What type of simulations are you doing?: I use global, regional and site-scale simulation, in both off-line and on-line mode.
- History of your work with ORCHIDEE: During my PhD with Katia Laval and Jan Polcher :
- I implemented a description of subgrid scale hydrology in ORCHIDEE-Choisnel : Ducharne A, Laval K, Polcher J (1998). Sensitivity of the hydrological cycle to the parameterization of soil hydrology in a GCM, Climate Dynamics, 14: 307-327.
- I showed how a better description of the soil's water-holding capacity could influence the simulated climate : Ducharne A, Laval K (2000). Influence of the realistic description of soil water-holding capacity on the global water cycle in a GCM, Journal of Climate, 13: 4393-4413.
- I developed the first routing scheme for ORCHIDEE : Ducharne A, Golaz C, Leblois E, Laval K, Polcher J, Ledoux E, de Marsily G (2003). Development of a High Resolution Runoff Routing Model, Calibration and Application to Assess Runoff from the LMD GCM. Journal of Hydrology, 280: 207-228.
More recently, with Frédérique Cheruy, Aurélien Campoy and Frédéric Hourdin, we showed the superiority of ORCHIDEE-Richards over ORCHIDEE-Choisnel when coupled to the LMDZ atmosheric model by comparaison with site-observation from the SIRTA observatory, and analysed the effect of the soil bottom's boundary condition (free drainage, impermeable bottom, or forced water table depth) on the surface fluxes and clocal climate :

- Campoy A , Ducharne A, Hourdin F, Cheruy F, Polcher J, Dupont JC, Haeffelin M : Influence of soil bottom boundary condition on land surface fluxes in a general circulation model, in prep.
- Potential future work with ORCHIDEE?: In a near future, my main project will be to develop a description of ground water that is consistent with ORCHIDEE's principles, sufficiently simple to be used at the global scale in the Earth system model, and sufficiently flexible to account for the various hydrogeological and topographical constraints.

- Primary objective of your current work with ORCHIDEE: In my current position, I am mainly working on the LPX model but I plan to do some ORCHIDEE simulations to update the work I have done during my PhD. By "update", I mean: doing the same simulations I have done before but with new updated climate forcing data (over the last years, after 2009).
I plan to use the ORCHIDEE version I developed during my PhD (ORCHIDEE with wetlands; ie. TOPMODEL to model the wetland dynamic and some routines to compute the CH4 flux densities; cf. "History of your work with ORCHIDEE" section).
But currently, this version cannot be run on any computer (I used to launch my ORCHIDEE version on MERCURE but Mercure stopped since the beginning of 2012).

- History of your work with ORCHIDEE: During both my 3‐year Ph.D. (LSCE) and my first short post‐doc (Bristol - 7 months), I have aimed to improve our knowledge of the relationships between climate and wetland methane (CH4) emissions at the global scale. My objectives were divided into three points: (i) to better understand the wetland CH4 emissions sensitivity to climate [Ringeval et al., 2010; Koven et al., 2011, Ringeval et al., 2012, in prep (cf. the "Potential future work with ORCHIDEE" section)] and to estimate the effect of this sensitivity on both (ii) the atmospheric CH4 concentration [Bousquet et al., 2011] and (iii) the climate through a potential feedback [Ringeval et al., 2011]. These three purposes covered different time scales: from year‐to‐year variability up to the millennial scale.
To reach these objectives, I implemented during my PhD the ORCHIDEE model with a wetland CH4 emissions scheme. I proceeded in two steps. The first one was the integration of a simplified version of TOPMODEL, a sub‐grid topographic model [Beven and Kirkby, 1979, Ringeval et al., 2012, submitted] to compute the wetland area dynamically. The second step was the integration of a based process model of CH4 flux densities [Walter et al., 2001]. The latter represents the mechanisms leading to CH4 flux to the atmosphere at the wetland site scale: production from the soil carbon pool, transport to the atmosphere and oxidation during this transport.

- Primary objective of your current work with ORCHIDEE: - Objective: use water isotopic measurements to better evaluate the hydrological processes in models. In particular: partition water budget of the soil column (drainage, surface runoff, transpiration, bare soil evap); continental recycling and its role in land-atmosphere feedbacks

- Project title, duration and supervisor/colleagues: 'Towards a more detailed representation of the energy balance in the coupled land surface model ORCHIDEE'; September 2011 - August 2014 with Sebastiaan Luyssaert and Philippe Peylin
- Primary objective of your current work with ORCHIDEE: I'm developing a new detailed and practical simulation of the energy budget within ORCHIDEE 1.9.5.2, coupled to the atmospheric model LMDZ.
As with other land surface models, the present release of ORCHIDEE has difficulties in reproducing consistently observed energy balances (e.g. Pitman et al., 2009; Jimenez et al., 2011; de Noblet-Ducoudré et al., 2011). Hence, the model must be improved to be better able to study the radiative effect of forest management and land use change. This observation serves as a starting point to this project – improving the level of detail in energy balance simulations of the surface layer.
The most in-depth simulations of surface layer energy budget are detailed iterative multi-layer canopy models, such as Ogeé et al. (2003). These are linked to specific measurement sites and do not interact with the atmosphere. In this current project, the aim is to create a model that will implement the insights obtained in those previous studies and improve upon the present ORCHIDEE parameterisation, but will run stably and efficiently when coupled to an atmospheric model.
This work involves a replacement of the existing allocation of 14 different types of vegetation within each surface tile (the 'Plant Functional Types') by a more granular scheme that can be modified to reflect changes in attributes such as vegetation density, leaf type, distribution (clumping factors), age and height of vegetation within the surface tile. There will be the implementation of more than one canopy vegetation layer to simulate the effects of scalar gradients within the canopy for determining, more accurately, the net sensible and latent heat fluxes that are passed to the atmosphere.
The model will include representation of characteristics such as in-canopy transport, coupling with sensible heat flux from the soil, a multilayer radiation budget and stomatal resistance, and interaction with the bare soil flux within the canopy space (and also with snow pack). The implicit coupling approach of Polcher et al. (1998) and Best et al. (2004) is to be extended to a multilayer scenario, and will then be tested and validated.
- What type of simulations are you doing?: For the moment I'm preparing a series of site scale runs as a first evaluation for the multilayer model, and as a comparison to the present ORCHIDEE simulation run on the same parameters. The simulations will be forced to begin with, but the code is written with coupling in mind, as this will be the next step.
- Potential future work with ORCHIDEE?: Simulation of interaction of snow packs underneath and above the canopy; mixing between grid squares at the surface layer; possible emission and interaction of chemical species?

- Primary objective of your current work with ORCHIDEE: The ORCHIDEE is validated against forest carbon dynamics observations after stand-replacing fires in North America. The ORCHIDEE_FM is used for this purpose. Validation data include Eddy-covariance measurements and field measures but mainly on the annual basis. The ORCHIDEE version is 1_9_5_2
- What type of simulations are you doing?: site scale/regional, forced
- Secondary objectives of the work you're doing with ORCHIDEE: for a regional carbon balance analysis.
- History of your work with ORCHIDEE: The ORCHIDEE_FM is validated against forest carbon dynamics observations after stand-replacing fires in North America.
- Potential future work with ORCHIDEE?: validate and use the model to simulate high latitude land surface- climate feedbacks.
