Description:
The Ocean Model Intercomparison Project
(OMIP) is an endorsed project in the Coupled Model Intercomparison
Project Phase 6 (CMIP6). OMIP addresses
CMIP6 science questions, investigating the origins and consequences
of systematic model biases. It does so by providing
a framework for evaluating (including assessment of systematic
biases), understanding, and improving ocean, seaice,
tracer, and biogeochemical components of climate and
earth system models contributing to CMIP6. Among the
WCRP Grand Challenges in climate science (GCs), OMIP
primarily contributes to the regional sea level change and
near-term (climate/decadal) prediction GCs.
OMIP provides (a) an experimental protocol for global
ocean/sea-ice models run with a prescribed atmospheric forcing;
and (b) a protocol for ocean diagnostics to be saved as
part of CMIP6. We focus here on the physical component
of OMIP, with a companion paper (Orr et al., 2016) detailing
methods for the inert chemistry and interactive biogeochemistry.
The physical portion of the OMIP experimental
protocol follows the interannual Coordinated Ocean-ice Reference
Experiments (CORE-II). Since 2009, CORE-I (Normal
Year Forcing) and CORE-II (Interannual Forcing) have
become the standard methods to evaluate global ocean/seaice
simulations and to examine mechanisms for forced ocean
climate variability. The OMIP diagnostic protocol is relevant
for any ocean model component of CMIP6, including
the DECK (Diagnostic, Evaluation and Characterization of
Klima experiments), historical simulations, FAFMIP (Flux
Anomaly Forced MIP), C4MIP (Coupled Carbon Cycle Climate
MIP), DAMIP (Detection and Attribution MIP), DCPP
(Decadal Climate Prediction Project), ScenarioMIP, High-
ResMIP (High Resolution MIP), as well as the ocean/sea-ice
OMIP simulations.
