The Research Repository for Data and Diagnostics (R2D2): An Online Database Software System for High Performance Computing and Cloud-Based Satellite Data Assimilation Workflows
摘要
The Joint Center for Satellite Data Assimilation (JCSDA) is a multi-agency research center established to improve the quantitative use of satellite data in atmosphere, ocean, climate and environmental analysis and prediction systems. At the JCSDA, scientists and software engineers within the Joint Effort for Data Assimilation Integration (JEDI) are developing a unified data assimilation framework for research and operational use. To harness the full potential of ever-increasing volumes of data from new and evolving Earth observation systems, a new online database software system has been developed and deployed by the JCSDA. As a core component of JEDI, the Research Repository for Data and Diagnostics (R2D2) performs data registration, management, and configuration services for data assimilation computational workflows. We present an overview of R2D2’s distributed system of data stores, SQL data model, intuitive python API, and user support efforts. In addition, we will detail R2D2’s utilization by environmental prediction applications developed by the JCSDA and its partners.
