This week JCSDA’s Eric Lingerfelt gave a 20 minute talk at the International Conference on Computational Science in Málaga, Spain. He presented the Research Repository for Data and Diagnostics (R2D2) component of the Joint Effort for Data Assimilation (JEDI) in the conference’s thematic track “Advances in High-Performance Computational Earth Sciences: Numerical Methods, Frameworks & Applications”.

In developing JEDI, one of the key requirements has been the storage of and access to rapidly growing volumes of data generated by new and existing observation systems. The R2D2 component is designed to fill this requirement. As a core component of JEDI, R2D2 performs data registration, management, and configuration services for data assimilation computational workflows. Eric presented an overview of R2D2’s distributed system of data stores, SQL data model, intuitive python API, and user support efforts, and discussed the use of R2D2 in environmental prediction applications by JCSDA and its partners. The peer-reviewed paper the presentation is based on has been published by the conference in Lecture Notes in Computational Science, Volume 14834. Both paper and presentation were a joint effort with contributions by Eric, Tariq Hamzey of NASA GMAO, and JCSDA core team members Maryam Abdi-Oskouei, Jérôme Barré, Fábio Diniz, Clémentine Gas, Ashley Griffin, Dominikus Heinzeller, Stephen Herbener, Evan Parker, Benjamin Ruston, Christian Sampson, Travis Sluka, Kristin Smith, and Yannick Trémolet. Congratulations to the entire team!
