The CMIP6 data request specifies the data which the endorsed MIPs have requested in order to complete their scientific objectives. Responding to pressure from modelling centres, the CMIP panel has specified that data should only be requested when there are specific plan to analyse that data. For any experiment, the data request allows modelling centres to determine not only the data requested but also, for each variable, to see who has requested and what scientific objective it is intended to support.
An email discussion between myself and Gokhan Danabasoglu at the start of February appeared to confirm that OMIP is not expecting to conduct and data analysis, and hence is not requesting data in the above sense. For this reason, the data request does not show OMIP requested data. The paper from Stephen Griffies at https://dl.dropboxusercontent.com/u/38722087/cmip6_ocean/WIP/OMIP_concerns_with_WIP_diagnostics.pdf
shows that their is some misunderstanding here.
OMIP has defined two experiments (named OmipA and OmipB in the current version of the data request). Currently, C4MIP is the only endorsed MIP requesting data from these experiments.
