AB: With a number of nascent, discipline-oriented VxOs (including a VSO, VHO, VITMO, ViRBO and two VMOs) under earnest development, time is ripe to investigate how the VxO paradigm may be extended to support cross- disciplinary science that has been the hallmark of Sun-Earth system science research. This presentation introduces a newly proposed Virtual Higher-Order Heliophysics Observatory [V(HO)²] to support global-scale (cross-disciplinary) Heliophysics research that require analysis of diverse datasets and models from different Heliophysics disciplines. The proposed coordinated effort will develop the V(HO)² to enable complex data queries with joint data conditioning, i.e., with filtering by context, content and/or region conditions. The higher- order querying capabilities will allow the generation of event lists for studying groups or classes of events with similar data features, and for studying relationships between events in separate regions (e.g., vortices in the magnetopause and spirals/pearls in the aurora). To support analyses of large-scale problems, such as in sun- solar wind, solar wind-magnetosphere or magnetosphere-ionosphere couplings, the V(HO)² will develop mechanisms to query different VxOs simultaneously, sequentially or iteratively to locate different pertinent discipline-data granules. To address the research challenges confronting the Heliophysics community, the V(HO)² will have the design objectives to: (1) enable solving new, global problems, (2) access diverse datasets and services, (3) enable wide-ranging (context-based and content-based) search capabilities to allow users to generate event lists and find related data (by context, content and/or location) of a particular event or groups of events, and (4) allow researchers to rapidly gain integrated views from the solar origin to the terrestrial effects of an event. The V(HO)² will collaborate with all existing VxOs, active Heliophysics data archives (e.g., the NASA SPDF) and future VxOs to develop seamless communications interfaces, and to develop uniform querying protocols to facilitate content-based search capabilities and to access the data files that fall within the time ranges generated by data searches.
