The Mediterranean Sea is undergoing and will undergo in the coming decades a wide variety of impacts from human activities (climate change, pollution from rivers, fisheries). Under these external forcings, its physics, marine biogeochemistry and marine ecosystems are transforming and evolving at a rapid pace. In order to better understand the past and characterize the future evolution of the Mediterranean Sea, we need to set up, validate and operate numerical models of the Mediterranean Sea that are realistic, reliable and able to run over long periods of time.
NEMOMED is the modeling platform of the Mediterranean Sea, based on the NEMO model and developed by the French community for more than 20 years, among others, at CNRM.
This contract aims mainly at the scientific improvement of this modeling platform and its exploitation for regional oceanic climate change studies. In particular, we aim to provide NEMOMED with a flexible and relocatable zoom capability to reach the kilometer scale, a better numerical scheme of ocean convection, a key phenomenon in Mediterranean oceanography, and a representation of the mixing effect of tides, in particular at the Strait of Gibraltar, the control point of the rest of the basin. The approach will be to develop these new capabilities in NEMOMED based on version 4 of the NEMO code available at CNRM, and on the network of scientists of the national project MEDIATION (see below), to perform evaluation simulations on case studies and then on long periods to finally obtain a new reference version of NEMOMED. This new version will have to be exploitable to carry out long term climate simulations on the past and the future.
The main missions of the proposed position are (1) to develop new functionalities in the NEMOMED code, (2) to ·aperform and evaluate adequate simulations, (3) to interact with the community of NEMO model developers within the CNRM, the MEDIATION project and beyond, and (4) to valorize the results obtained through scientific publications. The successful candidate will have a large degree of freedom concerning the development of the model beyond the aspects mentioned above and the scientific exploitation of the numerical simulations. The work will be carried out in the framework of the national project MEDIATION (see below).


The work proposed includes the following activities:
work on computer, participation to team meetings and project meetings, coordination and data exchange with the project partners, oral or poster communication at scientific conferences, publication of scientific articles, contribution to project deliverables.


1) A Ph.D. in atmospheric, oceanic or climate sciences, in informatics or in applied mathematics obtained before the starting date of the contract
2) Experience in one of the following scientific fields will be appreciated but is not mandatory: climate change, oceanography, numerical model development, ocean mixing processes, regional climate scenarios, Mediterranean Sea
3) Demonstrated skills in programming (NEMO code is in Fortran) and in a scientific analysis and plotting language (python, R, NCL or equivalent), and demonstrated experience working in a Linux environment (shell scripts, ...)
4) Experience in developing NEMO code and in particular the AGRIF refinement tool and mixing schemes, working on high performance computers and/or manipulating climate data (e.g. netcdf, nco, cdo format, ...) will be highly appreciated but is not mandatory
5) Excellent written and oral communication skills in English. Practice of the French language would be convenient but is not mandatory

Work Context

The Centre National de Recherches Météorologiques (CNRM, http://www.umr-cnrm.fr/ ) is a joint Météo-France and CNRS laboratory located in Toulouse, one of the most liveable and vibrant cities in France. It is one of the leading climate science research institutes in Europe. It provides a highly international and interdisciplinary environment for conducting scientific research as well as access to great scientific facilities.

The successful fellow will work in the regional climate modelling research team (https://www.umr-cnrm.fr/spip.php?article1035), a 13-member team, leaded by Samuel Somot (https://www.umr-cnrm.fr/spip.php?article437 ) including PhD students, postdocs, junior and senior researchers as well as research engineers. In addition to Samuel Somot, the close scientific environment will consist of Robin Waldman (https://www.umr-cnrm.fr/spip.php?article1057), Hervé Giordani and Florence Sevault.

The advertised position is funded by the national PPR Ocean & Climate MEDIATION project which involves many leading French research institutes in ocean sciences.
MEDIATION aims to radically transform integrated modeling methodologies by targeting two questions of major societal interest: how will global change impact the functioning of regional marine ecosystems, and how to assess the effect of environmental preservation measures? MEDIATION will focus on highly original methodological research intended to (i) develop scenarios with stakeholders that are consistent with practices, in order to inform decision-makers and guide public policies, (ii) define the appropriate level of complexity of the model chains to evaluate the response of ecosystems to these scenarios, (iii) quantify the uncertainty of models and model projections, (iv) process massive heterogeneous data to evaluate and improve the various modeling components, (v) reduce execution times to explore a large number of scenarios, and (vi) identify representative indicators of ecosystems and associated services in order to synthesize the information. The developments will be tested with two demonstrators selected in the French Atlantic and Mediterranean coasts.
