Realtime data fusion for climate monitoring, via process trellis

Climate monitoring projects, typically intended to gather and validate meteorological data and to serve as information frameworks for experiments, often have massive data‐gathering and data‐management requirements. The process trellis is a software architecture that meets these requirements. The trellis imposes a simple and regular organization on a complex, diverse set of parallel processes. The architecture is based on a hierarchical graph of decision processes, reflecting the conceptual hierarchy of the problem domain; all processes in the graph execute continuously and concurrently. The trellis has been implemented in the form of a domain‐independent shell (using the portable coordination language Linda). We describe the trellis structure and address trellis issues that seem particularly relevant to climate monitoring.
