Numerical Simulations Supporting Plasma Observatory Proposal: Working Group GIANNI

The ESA M7 mission candidate Plasma Observatory (PMO) proposes a seven-spacecraft constellation, to simultaneously measure plasma characteristics and gradients at both fluid and ion scales simultaneously, to investigate multi-scale cross-coupling processes in the Earth’s magnetosphere and around it. The proposal work is supported by several working groups, one of which is the Group on Simulation Numerical Support (GIANNI). The group is tasked with supporting the proposal's Science Study Team with simulation data, to help evaluate the proposal's science impact, assess possible descoping options and their effects on science output, and provide constraints for the PMO constellation parameters. This presentation introduces the group’s models and capabilities, including the wider collaborations with other working groups stemming from the tasks, such as evaluation of multipoint methods from simulation data. Plasma Observatory science objectives are reviewed with a focus towards numerical modelling avenues.
