Science Data From a Multi-Spacecraft, Multi-Scale Observatory: Data Processing, Selection, and Analysis for the HelioSwarm Mission

The HelioSwarm mission concept (HS), currently under phase A consideration for NASAs Heliophysics MIDEX Announcement of Opportunity, combines data across a multi-spacecraft observatory to probe the dynamics of turbulent near-Earth plasmas (solar wind, magnetosheath, and magnetosphere) at multiple spatial and temporal scales. The HS Science Operations Center (SOC) at UNH coordinates the production of scientific data across the observatory and its provision to the HS team and the public. We describe how heritage data processing techniques are used and extended to provide robust data sets for each spacecraft, including data sets merged across the instrument suite. These individual data sets are designed to support cross-spacecraft combinations for any desired multi-point analysis approach. The spacecraft in the observatory can be combined in hundreds of different ways to probe desired plasma scales with a range of techniques; the HS SOC provides tools to find times and combinations of spacecraft to meet the needs of any particular study. Preliminary versions of these selection tools are demonstrated, as well as the application of appropriate analysis techniques to selected synthetic data.
