Coordinating an operational data distribution network for CMIP6 data

Abstract. The distribution of data contributed to the Coupled Model Intercomparison Project Phase 6 (CMIP6) is via Earth System Grid Federation (ESGF). ESGF a network internationally distributed sites that together work as federated archive. Data records from climate modelling institutes are published and then shared around world. It anticipated CMIP6 will produce approximately 20 PB be ESGF. In addition this large volume number value-added services required interact with ESGF; for example citation errata both but not core part its infrastructure. With interacting CMIP6, CMIP Node Operations Team (CDNOT) was formed. CDNOT coordinated implemented series preparation challenges test all components in software ecosystem. This ensured when were released they could reliably distributed.
