Abstract:
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, sea-ice, land, and ocean -- each connected to the Coupler, and each exchanging data with the Coupler only.
The Climatological Data Atmosphere Model (datm) functions as the atmosphere component in a CCSM configuration. The datm atmosphere component interacts with the Coupler just like any atmosphere model would, but it is not an active model, rather, it takes atmosphere data from an input data file and sends it to the Coupler, ignoring any forcing data received from the Coupler. Typically the input data file contains mean daily data generated by an active CCSM atmosphere model (it's unlikely that real world observations exists for all the required fields). Such a "dummy" atmosphere model is useful for doing ocean + ice spinup runs.
The CCSM Climatological Data Atmosphere Model, version 6.0 (datm6), was released in June 2004, as part of the CCSM3.0 release. http://www.ccsm.ucar.edu/models/ccsm3.0/datm6/

Description:
The CCSM3.0 coupled model, released in June, 2004, provides the community with a coupled model framework for carrying out climate simulations. Upgrades from CCSM2.0.1 release can be found in the Introduction section of the Users Guide 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. In this sense, more than any particular component model, the coupler defines the high-level design of CCSM software.
