Job description
Context: Climate modeling lies at the heart of numerous studies ranging from the understanding of interactions and processes involved in climate changes to climate impact assessment and decision support. This research, involves model simulation,coupling of climate models and biogeochemical cycles as well as improved model versions that better represent small-scale processes. The IPSL climate model couples, in a modular way, a 3D atmospheric model, a 3D ocean model, a land surface model, a sea ice model and biogeochemical models in different compartments. The various configurations and uses lead to stronger requirements on the realism of the dynamics and physical characteristics of the climate. Model validation requires a dedicated approach, as the simple evaluation of individual components does not guarantee a smooth functioning of a coupled system. There is also a need to develop scientific strategies to identify the sources of bias in coupled models.
Model validation requires the input of many experts. It is also based on sets of diagnostics and analysis of various complexities allowing one to quantify the link between simulation results and observations which need to be maintained and advanced in accordance to current scientific issues.
Mission: Develop a strategy of quality assurance for the IPSL coupled model results in order to describe climatologies from a physical and dynamical point of view as well as to understand how bias in individual components or in couplings affect simulated climatology (mean state, climate variability, extreme events). This work, under the supervision of Drs. Pascale Braconnot and Olivier Marti, will be carried out through interactions with scientists and engineers who develop and exploit the IPSL climate model results. The candidate will integrate the “Climate modeling” team (run by Didier. Paillard, LSCE, France)
Activity breakdown:
This refers to the dynamical and physical parts of the IPSL climate model in its different coupled configurations (mean state, variability, process). Working time will be distributed in the following way:
1. Development of a series of diagnostics in order to permanently have a model whose main simulated climate characteristics are known and documented (~ 40% of the time). This work is part of the implementation of a strategy of quality assurance for the coupled model results. It will be carried out in collaboration with various experts and includes the analysis and synthesis of results as well as feedback on the quality of reference simulations.
2. Development of new reference versions of the model from sets of sensitivity tests (~ 30% of the time) in order to analyze improvements between the successive versions. The priorities for these steps will be defined in consultation with the development group of the coupled model.
3. Research to evolve the criteria and evaluation methods of the model (~ 30% of the time) in order to take better advantage of different model configurations and sets of simulations. This part will be defined in consultation with the researchers involved in the model evolution
Candidate profile
Skills: This engineer/scientist position addresses a candidate with a background in the physics and dynamics of climate, in climate modeling, in statistics, in analysis methods, and who has a strong interest in development of community tools (software).
Level: Masters degree (Ph.D. desirable).
Note: Interest in team work and ability to interact with many people are essential qualities for Interest in team work and ability to interact with many people are essential qualities for this position.
