Comparing Simulations to observations Future Predictions Emission Scenarios Model Spread WHAT IS CMIP? "THE INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE (IPCC) IS THE UNITED NATIONS BODY FOR ASSESSING THE SCIENCE RELATED TO CLIMATE CHANGE." WWW.IPCC.CH/ 62 ABSTRACTS AT AGU MENTION CMIP EXPLICITLY BUT PROBABLY MANY MORE USE THE DATA!

- Many 100.000s of individual datasets - Each dataset is identi fi ed by a unique id, consisting of 'facets' - Facets are part of CMIP controlled vocabulary (https:// wcrp-cmip.github.io/CMIP6_CVs/) - Unfortunately you still need to learn your vocabulary for now WHAT IS CMIP? - ORGANIZATION AND VOCABULARY https://wcrp-cmip.org/cmip-data-access/#access-routes CMIP Cycle MIP activity Modelling Center Model Code Experiment/forcing scenarios Ensemble member Output Variable Model Grid CMIP6.ScenarioMIP.NOAA-GFDL.GFDL-CM4.ssp585.r1i1p1f1.Omon.thetao.gn mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version di ff erent simulations components of a single simulation example MIP table used

- Reality: Large institutions create mirrors of parts of the archive, restricted to employees (data fortresses) - Large overhead, requires both expertise, time and funds - Individual access/data cleaning approaches might be incompatible, hindering reusability/reproducibility - E ff ectively limits conducting climate science to large legacy orgs WHAT IS CMIP? - TONS OF DATA!
