Postdoctoral Research Fellow in Terrestrial Carbon Cycle Modelling

Université d’Oslo, Norvège

Titre du poste : Postdoctoral Research Fellow in terrestrial carbon cycle modelling

Description du poste : Ce poste de chercheur postdoctoral est proposé par le Département des géosciences de l’Université d’Oslo. La date de début est immédiate, et le contrat est à temps plein pour une durée de trois ans, incluant 10% du temps dédié à des activités professionnelles essentielles pour le développement de carrière, généralement par le biais d’activités d’enseignement. Il est à noter qu’aucune personne ne peut être désignée pour plus d’un poste de chercheur postdoctoral à l’Université d’Oslo.

Description du projet : Le projet « NorSink » a pour but d’améliorer la compréhension du cycle du carbone terrestre, un sujet de haute importance étant donné que l’absorption nette du carbone par les systèmes terrestres en Norvège est estimée à 20-25 MtCO2e/an, représentant environ 50% des émissions de gaz à effet de serre d’origine anthropique. Bien que cette absorption ait connu une tendance positive entre 1990 et 2010, cette dynamique s’est inversée, et les raisons de cette inversion ne sont pas totalement comprises. Le projet se concentre sur six activités clés :

• Intégration de bases de données norvégiennes dans des modèles basés sur des processus.
• Modélisation innovante des perturbations forestières.
• Modélisation plus robuste de l’accumulation de carbone dans le sol.
• Utilisation de nouvelles données provenant de tours de flux dans des zones à haute altitude et en latitude élevée.
• Inclusion des flux riverains et de biomasse dans les budgets de carbone.
• Fourniture de données de référence pour l’inclusion du carbone océanique et côtier.

Ce projet est un effort collaboratif impliquant plusieurs institutions de recherche norvégiennes, soutenu par le Conseil de Recherche Norvégien, et sera supervisé par des experts en modélisation des données.

Fonctions et responsabilités : Le chercheur postdoctoral se concentrera sur l’amélioration et l’application du modèle de surface terrestre CLM, utilisé dans le Modèle du Système Terrestre Norvégien. Ce modèle sera associé à FATES et MIMICS+ pour simuler la décomposition du carbone dans le sol et la dynamique des écosystèmes terrestres.

Compétences requises : Le candidat idéal devrait posséder :

• Un diplôme équivalent à celui d’un docteur en sciences naturelles avec un accent sur la modélisation (géosciences, physique, chimie, biologie, etc.).
• Une bonne connaissance des langages de programmation et d’analyse de données tels que Fortran, Matlab, ou Python.
• Une expérience en modélisation de systèmes naturels et en assimilation de données basées sur des données observationnelles.
• Des compétences avérées en communication écrite et orale en anglais.
• Une capacité documentée à publier dans des revues internationales de premier plan.

Qualifications souhaitées :

• Expérience de terrain.
• Expérience avec le calcul haute performance (HPC).
• Expérience dans la supervision d’étudiants.

Conditions de travail : À l’Université d’Oslo, nous valorisons un environnement de travail inclusif et diversifié. Les candidats dotés de responsabilités envers la société, y compris ceux ayant un arrière-plan d’immigration, sont particulièrement encouragés à postuler. La rémunération pour le poste de chercheur postdoctoral est comprise entre 585 800 NOK et 668 000 NOK selon la compétence et l’expérience, avec une déduction de 2 % pour le Fonds de pension d’État.

Comment postuler : Les candidatures doivent comprendre :

• Une lettre de motivation.
• Un CV détaillant l’éducation, les postes occupés, et l’expérience pédagogique.
• Des copies de diplômes et de relevés de notes.
• Une liste complète des publications et jusqu’à 5 travaux académiques à considérer par le comité d’évaluation.
• Les noms et coordonnées de 2 à 3 références.

Les candidatures doivent être soumises via le système de recrutement Jobbnorge. Toutes les pièces justificatives doivent être en anglais ou dans une langue scandinave.

À propos de l’Université d’Oslo : En tant qu’institution de recherche et d’enseignement supérieure de Norvège, l’Université d’Oslo abrite 26 500 étudiants et 7 200 employés, contribuant significativement à la recherche et à l’éducation en géosciences, et participant activement aux Objectifs de Développement Durable de l’ONU.

📝 Description du poste : Postdoctoral Research Fellow in terrestrial carbon cycle modellingAbout the positionPosition as Postdoctoral Research Fellow available at Department of Goesciences.Starting date as soon as possible.The appointment is a fulltime position and is for a period of three years (10% of which is devoted to other career promoting work, usually in the form of teaching activities).No one can be appointed for more than one Postdoctoral Research Fellowship at the University of Oslo.Project descriptionThe net uptake of carbon to terrestrial systems (LULUCF) in Norway is estimated to be 20-25 MtCO2e/yr or about 50% of the anthropogenic greenhouse gas emissions. However, the positive trend in the estimated uptake between 1990 and 2010, has since then been reversed. The reason for this reversal is not fully understood, although similar trends are observed across Europe. The aim of NorSink is to improve the knowledge base for decision making through six key activities:

• assimilating rich Norwegian datasets into process-based models
• novel modelling of forest disturbances
• more robust modelling of soil accumulation
• utilise new flux tower data in high-altitude and high-latitude areas
• inclusion of lateral riverine and biomass fluxes into carbon budgets
• provide baseline data for the inclusion of ocean and coastal carbon

NorSink will lead to a step change in the emerging science of carbon budgets and forecasting, and provide decision makers with the knowledge to design effective climate policies as Norwegian and European carbon sinks dynamically evolve under climate change.The postdoc will work on improving and applying the land surface model CLM (Community Land Model) that is used in the Norwegian Earth System Model (NorESM). In the project, the CLM model will be using the FATES (Functionally-Assembled Terrestrial Ecosystem Simulator) terrestrial ecosystem model and the MIMICS+ module for soil carbon decomposition. FATES simulates and predicts growth, death, and regeneration of plants and subsequent tree size distributions by tracking natural and anthropogenic disturbance and recovery. It does this by allowing plants with different traits to compete for light, water, and nutrients. MIMICS+ is microbial explicit module to simulate soil carbon decomposition and nutrient cycling, by including growth and decay of saprotrophs (bacteria and fungi) as well as mycorrhiza fungi.The postdoc will work together with UiO expertise on data assimilation to calibrate the coupled CLM-FATES model using:

• Snow cover
• Flux tower data

The idea is to combine established iterative ensemble Kalman methods with novel emerging machine-learning-enabled model calibration techniques recently adopted in CLM-FATES at UiO.The aim is:

• to constrain snow-related parameters
• to constrain the dominant drivers of photosynthesis, aggregated to species level (for trees) and functional type (for non-forest systems).

The Department of Geosciences (IGF), University of Oslo (UiO), invites applications for a Postdoctoral Research Fellow in terrestrial carbon cycle modelling. This position is associated with the recently funded project « Norway’s carbon sink under climate change (NorSink) » supported by the Norwegian Research Council.
