Causes of uncertainties in the representation of the Arabian Sea oxygen minimum zone in CMIP5 models

Global models show generally a large model-data misfit with regard to oxygen. One of the most intense OMZs is located in the Arabian Sea. The scripts serve to give an overview of the main model deficiencies in the Indian Ocean with a detailed comparison of the historical state of ten climate models from the 5th coupled model intercomparison project (CMIP5) that present our present-day understanding of physical and biogeochemical processes.
