1. CMIP6 use case and adoption of RDA outputs
PITs, typing, collections, brokering, fabric, ...
RDA chairs meeting, NIST, Dec 12, 2016

2. Coupled Model Intercomparison Project (CMIP)
Run by the World Climate Research Program to compare climate models to assess their differences, quality and uniqueness
Simulation of agreed experiments based on common forcing data
Large-scale activity involving many research groups
Modelling data – not observational data

3. Each phase of CMIP runs for several years CMIP phase 6:
Current effort: CMIP6
Each phase of CMIP runs for several years
Interconnection between CMIP and IPCC ARs
CMIP phase 6:
Data production expected to begin in 2017
Lasts 3 to 4 years (plus further usage of archives)
Data volume in excess of 50 PB
All CMIP6 files receive Handles and PITs according to a profile (this is already in place)
multiple 100 millions of Handles

10. Test Handles / Landing page demo access
To play with the landing page, please check out the test handle hdl: /f21e70e8-beda e7-af ac using any DOI resolver…
To view the contents of a handle record, please checkout

11. Publication demo (Video – 1 minute, please use Chrome)
The publisher automatically assigns PIDs to datasets and sends messages to RabbitMQ (console output)
Messages are received by RabbitMQ (monitoring GUI)
Watch how a user gets a PID for a custom set of datasets
