Analysis and Synthesis

The Analysis and Synthesis SN provides the core services needed for the analysis of observations and their synthesis into derived data products and visualizations. It provides the principal interface to science and education users. Users access the Analysis and Synthesis subsystem through the Interactive Analysis and Visualization services, and interact with the Event Detection Framework and the Data Assimilation and Model Integration Framework. In each case, the user provides specifications and rules, process definitions, and key decisions to the framework, and receives refined datasets, analysis and visualizations.

The Data Assimilation and Model Integration Framework and the Event Detection Framework represent archetypical activities carried out in an analysis and synthesis effort. The Data Assimilation and Model Integration Framework hosts prognostic and retrospective numerical models, usually involving assimilation of real-time or retrospective data from instruments or data repositories, and publishes model products and their descriptors to which interested users can subscribe via the Exchange.

The Event Detection Framework node operates as a filter on real-time or retrospective data to provide detected and classified events as a product. It receives process specifications to establish trigger conditions, definitions and patterns for events, and qualified data or model products via the Exchange.

The Workflow Framework provides support for the definition, integration and enactment of user-defined workflows, ranging from human-in-the-loop data QA/QC to event detection and model integration. It provides a workflow engine based on the process execution services of the CEI.

Virtual Collaboration Management provides the foundation for definition of virtual observatories, laboratories and classrooms. This enables a virtual collaboration of multiple individuals in distributed locations in the setting of a defined project using the same set of physical and virtual resources. The capabilities provided include definition of a project by a project lead role, invitation of individuals to collaboration, selection of the resources available to all project members, management of project membership and resource use policy, use of data processing, analysis and visualization tools, the capability to define workflows and the publication of results to the public.
