Motivation: Interaction of hydrological cycle with other global changes is affecting ecosystems on Earth. Landscape Evolution Observatory (LEO) is an interdisciplinary project at Biosphere 2 aimed to quantify the interactions between soils, biological, hydrological, geological and atmospheric processes. To develop a good u
Background and Current State: LEO experiments are characterized by large amounts of the data streaming and processing to effectively study hydrological cycles and their interactions with environment. Ring Buffer Network Bus (RBNB) Data Turbine is an open source initiative to develop an infrastructure for data management, processing and synchronization. Kepler is another open so..ware tool for scientific workflow management. In parallel we also set up a physical experimental testbed in the B2. The test bed consists of 30 sensors to monitor features such as the weight, water flow, and conductivity with an operational infrastructure to simulate rain on the test bed. National Instrument’s Compact RIO is programmed with the LabView to collect and store data in real time. However, the experimental test bed and the workflow management components have not been integrated yet.
Project Goals: To enable seamless coupling of computational models with the unique experimental infrastructure of Biosphere 2 (B2). We propose a service-oriented cyber- infrastructure shown in figure 1 for establishing a distributed system which integrates physical infrastructure at B2 with data assimilation models executing on a virtualized
cloud platform with hundreds of cores available at Autonomic Computing Lab at University of Arizona. Our objective is to develop strategies for robust data acquisition, autonomic
decision making in sensing, data-model fusion, analysis and visualization to support accelerate research and discovery.
