Abstract
This project describes how researchers will support data collections and management of a proposed Next-Generation Ecosystem Experiments (NGEE) Arctic Phase 4 to allow for coordinated data use among an interdisciplinary team of empiricists and modelers, as well as how the team will continue to provide a foundation of open science and data sharing through an NGEE Arctic Managed Project Data Space.
The NGEE Arctic Data Management Team (DMT) recognizes the need for coordinating a collection of baseline datasets that support the modeling activities of three proposed Phase 4 model-experiment questions and three proposed Phase 4 crosscut science activities. These datasets range widely from synthesized model evaluation site data to regional and pan-Arctic initialization, parameterization, and evaluation data. Scaling activities will determine NGEE Arctic data standards, ensuring coordination of research activities and facilitating data interoperability. The DMT will create and foster a Managed Project Data Space and an associated data catalog that will be a compute resource providing open and shared access to an organized collection of datasets. Phase 4 Science Teams will both contribute to and access these organized data thereby ensuring data coordination across modeling activities, reducing duplication of effort, mitigating model uncertainties, and fostering consistent workflows. This compute and data access resource will be an allocation of Oak Ridge National Laboratory’s (ORNL) Scalable High Performance Computing Condo known as the Compute and Data Environment for Science (CADES). CADES’ Open Protection Zone allows researchers inside and outside of ORNL access to dedicated infrastructure, sustained storage and access, compute resources, and customizable software as a service. The DMT will develop the infrastructure and manage a data catalog that allows easily searchable high-level metadata for site, regional, and pan-Arctic datasets and provides contextual information of spatial and temporal extents and resolutions of data. The DMT will assist Phase 4 researchers with publishing all mature datasets into DOE’s Environmental System Science Data Infrastructure for a Virtual Ecosystem long-term repository.
