It has become apparent from climate models, instrumental observations, proxy and historical records, that eruptions reaching high into the atmosphere (i.e. stratosphere) can have a significant global cooling effect, that they have modulated past climate variability and may contribute to mitigate anthropogenic global warming in the 21st century. Such volcanic effects are now recognized in near-term decadal prediction systems through idealized climate model scenarios and initialized ocean conditions. Based on the complementary scientific expertise of an international consortium, the Synergia CALDERA project aims at exploring the processes/mechanisms controlling volcanic aerosols distribution and life cycle after large stratospheric eruptions and their effects on global modes of climate variability (such as the AMOC, ENSO, IPO or monsoons) over the last 2000 years and during the 21st century.
The partners of the project invite applications for the following position:
The successful candidate will design model experiments with the IPSL Ocean-Atmosphere Global Climate Model (OAGCM) including interactive aerosol microphysics to investigate the formation and evolution of volcanic aerosols, reconstruct volcanic forcing, and simulate the impacts on the global climate system. The post-doctoral scientist will use estimates of volcanic sulphur loadings inferred from ice cores for the largest eruptions of the last 2000 years and perform short experiments for key eruptions of the Common Era (CE). The first objectives will be to simulate the time-varying distribution, size and optical properties of volcanic aerosols for the different eruptions, assess the uncertainty ranges of reconstructed volcanic forcing, and study the general climate response including the possible impact on the ozone layer following the eruptions.
In collaboration with the other scientists of the project, the post-doctoral scientist will investigate how the simulated volcanic forcing can influence climate variability in interaction with well-established global climate variability modes, and evaluate the simulations against climate proxy and historical records. All the model development and running experiments will be carried out with the support of the IPSL project team (including a computing engineer) so that the post-doctoral scientist can be fully involved in scientific analyses and publication of the results in peer-reviewed journals. Detailed studies will also be carried out to assess the climate impacts of probabilistic volcanic eruptions scenarios on future climate projections.
The activity of the LOCEAN host team (VARCLIM) focuses on the study of physical processes that control the dynamics and variability of the ocean and climate on a wide range of time and space scales for a better understanding of the climate system and its present, past and future evolution. The LOCEAN laboratory (https://locean-ipsl.upmc.fr) is one of nine laboratories in Ile-de-France in environmental and climate sciences at the Institut Pierre-Simon Laplace (IPSL) (https://www.ipsl.fr). The close synergy between LOCEAN's scientific teams and other IPSL laboratories within the IPSL Climate Modelling Centre (https://cmc.ipsl.fr) allows research and development of a climate model based on the integration of several components for the atmosphere, ocean, sea ice and continental surfaces. It regularly participates in international exercises such as the Climate Model Intercomparison Project (CMIP), on which the work of the Intergovernmental Panel on Climate Change (IPCC) is based. The modelling activity is based both on GENCI's major national computing centres and on a dedicated IT infrastructure located at IPSL. The post-doctoral scientist will join a very dynamic scientific team at LOCEAN/IPSL and will work closely with teams from LATMOS/IPSL and with about ten engineers and researchers who are at the heart of the development of the IPSL climate model. The position is based on the Pierre et Marie Curie campus of Sorbonne University in Paris.
- PhD in climatology, Earth science or related field (physics, informatics)
- Publication(s) in peer-reviewed international journals
- Solid experience in programming and in managing large data sets
- Strong motivation and interest for a research career
- Demonstrated verbal and written communication skills in English
- Interest in working in a multidisciplinary environment.
Employment situation and conditions
The recruited post-doctoral scientist will work in collaboration with experienced LOCEAN, LATMOS and IPSL researchers and engineers and will collaborate closely and regularly with the IPSL-CMC group.
