Multi-Point Data Analysis Methods

The Multi-Point and Advanced Data Analysis Methods Working Group has been established to support the mission’s Science Study Team (SST) in evaluating how PO’s science goals can be achieved through its unique configuration. To address these objectives, PO will deploy a constellation of seven spacecraft in a double-nested tetrahedral configuration with a common vertex, enabling simultaneous measurements at both fluid and ion scales and, crucially, their coupling. Compared to previous multi-spacecraft missions such as Cluster and MMS, PO’s expanded constellation introduces unprecedented opportunities to resolve multi-scale dynamics in space plasmas. However, these opportunities come with significant challenges. Realizing PO’s full scientific potential requires the development and application of novel multi-point and advanced data analysis methodologies capable of exploiting measurements from more than four spacecraft. The Working Group brings together expertise in multi-spacecraft diagnostics and the analysis of in situ plasma observations.
