Several ocean reanalyses products are produced worldwide with different purposes and methodologies. The joint GODAE OceanView/CLIVAR-GSOP workshop in Santa Cruz (13-17 June 2011, Oke et al 2011) called for a community action on exploitation of the latest ocean reanalyses for real time climate monitoring and intercomparison. The first stage would be to complete an Ocean Reanalysis Intercomparison Project (ORA-IP), although the ultimate goal would be near realtime monitoring of the ocean through indices based on an ensemble of re-analysis.

A viable proposal was put forward in Santa Cruz, based on the criteria of minimum effort. The following procedure was proposed:

A) Production centers, including Operational and Reanalysis centers to provide relevant information (gridded fields of basic primary variables) in agreed formats and grids (where applicable), to enable the agreed intercomparison procedure.

B) Processing centers. For intercomparison purposes each processing centre would take on a particular variable in which that have a strong interest and expertise. They would then be responsible for the intercomparison and eventually monitoring of that variable. They would process ensemble statistics based on the input from the individual production centers, and create relevant indices or metrics or graphics which could be directly compared.
