For this purpose, advanced high resolution carbon-waterenergy models will be used. Two models will be run over the period 1994-2007 at a spatial resolution of 8 km and hourly time step with new climate forcing data from Meteo France. It is the first time that such high resolution will be attained in large scale terrestrial carbon modelling. The two models are the SURFEX platform (ISBA) of Météo-France, and the ORCHIDEE model developed at IPSL. The post-doctorate fellow will perform the SURFEX simulations, and compare SURFEX and ORCHIDEE results. The simulations will be tested against agricultural statistics, biometric measurements, and remote sensing observations that are part of the CARBOFRANCE project. Exciting new scientific publications in peer-reviewed journals are expected. The net monthly salary will be about 2400 Euro before income tax. Application should be done by email by sending a resume, CV, and the names, telephone and email address of 2 referees to: jean-christophe.calvet@meteo.fr The closing date for applications is 20 March 2005. The candidate should be familiar with programming languages (Fortran) and have notions of graphic softwares (PVWave, Matlab, or IDL). Knowledge of land surface models is recommended. The successful applicant will be expected to start in May 2007. ===================================== Post-doctoral fellowship at LSCE Laboratoire des Sciences du Climat et de l’environnement) (CEA-CNRS-UVSQ) Applications are invited for 18 months post-doctoral research fellowship starting April 2008, at LSCE (CEA) near Paris, France, in the Biogeochemical modelling team (http://www.lsce.ipsl.fr/) to work on the following subject: ===================================== Decennial simulation of carbon fluxes at few stations: comparison with eddy-covariance fluxes and ecosystem data (18 months contract) Project: CarboFrance The CarboFrance project (2008-2010) funded by the French Ministry of Environment, aims at assessing the impact of the seasonal and interannual variability of climate on ecosystem CO2 fluxes and carbon stocks over France. For this purpose, two state of the art carbon-water-energy models will be used and compared to eddycovariance fluxes and ecosystem measurements made at more than 10 sites in France (part of the CarboFrance project). In a parallel task of the project a synthesis of the different processes controlling the variability of the carbon fluxes will be achieved. The objective is to thus confront model simulations to these data in order to improve/validate our understanding and predictive capacity of the impact of climate extremes on carbon fluxes. The two models are the SURFEX platform (ISBA) of Météo-France, and the ORCHIDEE model developed at IPSL. They will be run at hourly time step with local climate forcing from the different sites. The post-doctorate fellow will perform the ORCHIDEE simulations at the different sites, and compare SURFEX and ORCHIDEE results at each site with ecophysiological data. Exciting new scientific publications in peer-reviewed journals are expected. The net monthly salary will be about 2400 Euro before income tax. Application should be send by email with a resume, CV, and the names, telephone and email address of 2 referees to: peylin@lsce.ipsl.fr The candidate should be familiar with programming languages (i.e., Fortran) and graphic softwares. Knowledge of ecophysiology is also recommended. ===================================== Post-doctoral fellowship at LSCE Laboratoire des Sciences du Climat et de l’environnement) (CEA-CNRS-UVSQ) Applications are invited for 18 months post-doctoral research fellowship starting April 2008, at LSCE (CEA) near Paris, France, in the Biogeochemical modelling team (http://www.lsce.ipsl.fr/) to work on the following subject: ===================================== Improving soil organic matter dynamics modelling at regional to global scales (18 months contract) Project: CarboSol The CarboSol project (2008-2010) funded by the Groupement d'intérêt scientifique (GIS) ”Climate-Environment-Society”, aims at an improved understanding of the vulnerability of soil organic matter to global change. For this purpose, the project aims at improving existing models of soil organic matter dynamics based on the complementary expertise of the participating research institutions (BIOEMCO, ESE, LSCE). The objective is to integrate knowledge from new and existing (manipulative) field studies and theoretical modeling approaches to improve soil organic matter dynamics models at the large scale. The four major topics to be addressed are: a) the sensitivity of decomposition processes to temperature and humidity, b) the control of decomposition through substrate and microbial biomass, c) the effect of vertical profiles, and d) effects of soil management. The post-doctorate fellow will help to generalize novel point-scale modeling approaches to improve soil organic matter modeling in the global dynamic vegetation model ORCHIDEE developed at IPSL. The generalized model will be evaluated and calibrated against CarboSol datasets in close collaboration with soil scientists at BIOEMCO. Finally, new model will be used to assess the vulnerability of regional and global soil carbon stocks to global change. Exciting new scientific publications in peer-reviewed journals are expected. The net monthly salary will be between 2000 and 2500 Euro before income tax depending on qualification. Application should be send by email with a resume, CV, and the names, telephone and email address of 2 referees to: Soenke.Zaehle@lsce.ipsl.fr peylin@lsce.ipsl.fr The successful candidate will have a background in environmental modelling and some knowledge of soil sciences. Knowledge of at least one programming language (i.e., Fortran) and graphic software is essential. ===================================== Post-doctoral fellowship at LSCE Laboratoire des Sciences du Climat et de l’environnement) (CEA-CNRS-UVSQ) Applications are invited for 10 months post-doctoral research fellowship starting April 2008, at LSCE (CEA/CNRS) near Paris, France, in the Biogeochemical modelling team (http://www.lsce.ipsl.fr/) to work on the following subject: =================================== Modeling of climat change impact on permafrost biogeochemistry (10 months contract) Project: IMPACT-BOREAL The IMPACT-BOREAL project, funded by the French Agence Nationale de la Recherche (ANR), aims to understand the impact of climate change on hydrology and methane production in anaerobic soils in boreal regions. Based on the complementary expertise of the participating research laboratories (LSCE, LERMA, LEGOS, CNRM and LGGE), the project is articulated around four axes, a) development of hydrology and biogeochemistry of boreal ecosystems, b) evaluation of wetlands dynamics using remote sensing data, c) evaluation of methane dynamics using historical and ice core record and d) impact of climate change on methane emissions. The post-doctorate fellow will integrate an existing model of permafrost biogeochemistry in ORCHIDEE, the dynamic global vegetation model of IPSL. This will allow to estimate the thermal and hydrological conditions of permafrost soil and to evaluate their soil carbon decomposition leading to atmospheric sources of CO2 and CH4. The seasonal as well as the long term dynamic of the model will be evaluated against available data. Impact of future climate change on permafrost extent and emissions of carbon dioxide and methane will be estimated, allowing to investigate the potential for a positive feedback between climate change and permafrost melt. Exciting new scientific publications in peer-reviewed journals are expected. The net monthly salary will be about 2400 Euro before income tax. A 6 month extension beyond the initial contract should be possible. Application should be send by email with a resume, CV, and the names, telephone and email address of 2 referees to: pierre.friedlingstein@lsce.ipsl.fr The successful candidate will have a background in environmental modelling.
