10. Managed by UT-Battelle for the U. S. Department of Energy ESG Integration: Next Steps  Support search of non CF-compliant variables  Spatio-temporal search support – ORNL will lead this effort in the ESG community  More flexible data model – In collaboration with NCAR and NASA JPL  Enhanced search API and web intelligence – Support both RDF triple store and Next Generation Search Technologies  Flexible data publishing workflow – Incremental, continuous, automated agents – In collaboration with LLNL  Soliciting feedback on CDIAC user community requirements

Department of Energy Synergistic Activities – UV-CDAT  The Ultra-scale Visualization – Climate Data Analysis Tools (UV-CDAT) – An integrated framework for end-to-end data analysis and visualization of climate model and observational datasets – Provenance, Workflow and automated inter-comparison (both model/model and model/observations)

12. Managed by UT-Battelle for the U. S. Department of Energy Summary  We published several high impact observational datasets and made them available to a broader community  We made good progress on identifying the limitations of the current system and identifying areas of improvement  We have developed a path forward to fully integrate high-impact Observational Datasets within ESG  We developed a collaborative relationship between the ESG and observation dataset community and are playing an active role in extending ESG to support their requirements
