Missions

The successful candidate will participate to the development of the LMDz-INCA global climate-chemistry-aerosol model and apply the model to investigate the impact of a hydrogen economy on atmospheric composition and climate. The candidate will also contribute to the model evaluation through the comparison of the results with satellite and ground-based observations of hydrogen or hydrogen precursor gases. The final objective will be to perform simulations of hydrogen leakages to the atmosphere under various future scenarios and investigate the impact on climate forcings and on pollutants. In addition to these scientific activities, the candidate will participate to the project regular meetings in Europe and will present results at international conferences on hydrogen or atmospheric sciences in general. The researcher will work under the scientific responsibility of Didier Hauglustaine, and will be part of a larger project team, including specialists with different expertise.

Activités

• Contribute to the development and improvement of a version of the LMDZ-INCA global model including an interactive and emission driven simulation of hydrogen, methane and ammonia.
• Improve in particular the parameterization of the hydrogen soil uptake based on the ORCHIDEE vegetation and soil model.
• Perform a set of simulations with the global model in order to investigate the atmospheric budget of hydrogen and its precursor gases, evaluate the model results against observations and against other models. As a second step perform impact simulations in order to investigate the impact of a hydrogen economy on future atmospheric composition and climate.
• Write and publish articles in peer-reviewed journals that highlight findings from the research project.
• Communication of research results at international conferences/meetings and on the occasion of regular lab meetings.
• Contribute to the HYway project reporting and ensure a smooth collaboration with the project partners.

Compétences

• You hold a PhD in physical, atmospheric or environmental sciences.
• You have a good experience in numerical modelling and running computer code on High Performance Computing centers.
• You have good programming skills on LINUX systems. A specific experience with Fortran and Python is valuable.
• Proficiency in English and good writing skills.

Contexte de travail

The Laboratoire des Sciences du Climat et de l'Environnement (LSCE) is developing and using in collaboration with Institute Pierre Simon Laplace (IPSL) partners a global atmospheric chemistry-aerosol-climate model coupling both the troposphere and the stratosphere. We are proposing a grant-holder position to a person to be involved in research activities in our team in the framework of the HYway European project. There is an increasing global interest in molecular hydrogen (H2) as an energy vector. Hydrogen can be used for efficient storage and transportation of energy from other sources. HYway will use a wide range of models at different scales, new and existing measurements, and innovative development of hydrogen emission scenarios to quantify the climate and environmental risks and co-benefits of a hydrogen economy.
