Séminaire PMMH - Hannah Allen (LSCE, CEA Saclay)
Monitoring atmospheric fossil fuel emissions using radiocarbon and global atmospheric simulations with a transport and inverse modeling system
Independent monitoring and apportioning of CO2 emissions is crucial for the verification of greenhouse gas reductions targeted by international agreements designed for climate change mitigation and adaptation. Radiocarbon (14C), found as a fractional isotope of CO2, can be used as a key tracer for fossil-derived CO2 and thus aid in the accurate apportioning of measured CO2 that arises from fossil fuel sources compared with other emissions sources. As part of the Horizon Europe CORSO project, we expanded a dedicated atmospheric transport modeling and variational inversion system to include radiocarbon in order to assess fossil CO2 emissions estimates at the global scale. The system is based on the assimilation of CO2 and 14CO2 measurements that are collected using central-European atmospheric ICOS stations combined with global background stations. The modeling and inversion framework is based on the Community Inversion Framework (CIF) coupled to the LMDZ global transport model with fluxes and isotopic signatures from terrestrial, oceanic, fossil fuel, nuclear, and cosmogenic sources. We conduct a multi-decadal analysis of the CO2 and 14CO2 emissions derived from this framework.

Séminaire PMMH - Ludovic Berthier, Gulliver
Vendredi 24 janvier de 11h00 à 12h00 - Salle réunion PMMH 1
Emerging active turbulence and chaotic advection in dense active matter
I will show that active mesoscale flows, a.k.a. active turbulence, leading to chaotic advection generically emerge in simple models of active particles leading to streams and vortices reminiscent of multiscale flow patterns in turbulence. The characteristics of these flows do not depend on the specific details of (...) -

The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
