Summary

Abstract: The Climatological Data Land Model (dlnd) functions as the land component in a CCSM configuration. The dlnd land component interacts with the coupler just like any land model would, but it is not an active model, rather, it takes land 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 monthly data generated by an active CCSM land model (it's unlikely that real world observations exist for all the required fields). Such a "dummy" land model is useful for doing ocean + ice spinup runs. The CCSM Climatological Data Land Model, version 6.0 (dlnd), was released in June 2004, as part of the CCSM3.0 release. 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.

This release includes the CSIM source code, documentation, input and forcing data.

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.
