What is a "Data Ocean Model" ?
CCSM coupled model is based on a framework which divides the complete climate
system into component models connected by a coupler. This design
requires four component models -- atmosphere, land, ocean, and sea-ice --
each connected to the coupler, and each exchanging data with the coupler only.
From a software engineering point of view, the CCSM is not a particular
climate model, but a framework for building and testing various climate models
for various applications.
The Climatological Data Ocean Model (docn5) functions as the ocean component in
a CSM configuration. The data ocean component interacts with the flux coupler
just like any ocean model would, but it is not an active model. Rather, it
takes SST data from an input data file and sends it to the coupler, ignoring any
forcing data received from the coupler. The input data file may contain either
climatological SST data (e.g. from Shea, Trenberth, & Reynolds) or a time series
of multi-year data. Such a "data model" is useful for coupling active
atmosphere and land models with climatological or multi-year SST forcing data.
