12. COUPLED MODEL INTERCOMPARISON PROJECT The objective of CMIP is to better understand past, present and future climate changes arising from natural, unforced variability or in response to changes in radiative forcing in a multi-model context.

19. - Data is distributed via the Earth System Grid Federation (ESGF) - Federation of public sector data centers hosting CMIP data (and more) on their servers. - Licensed, public, free - Data nodes serve netcdf fi les primarily to download. ESGF
20. - 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 CMIP DATA: CHALLENGES ESGF Custom Code Custom Code Custom Code University Lab Industry ❌ ✋🚫
