The DCESS Earth System Model contains at present atmosphere, ocean, ocean sediment, land biosphere and lithosphere modules. An additional methane hydrate module is included in version 1.2 and an ice sheet module will be developed in the future. Sea ice and snow cover are di­agnosed from estimated meridional profiles of atmospheric temperature. The model is divided into two 360° wide zones by 52° latitude. The model ocean is 270° wide and extends from the equator to 70° latitude. In this way the ocean covers 70.5 % of the Earth surface and is divided into low-mid and high latitude sectors in the proportion 84:16. Each ocean sector is divided into 55 layers with 100 m vertical resolution to maximum depths of 5500 m. Each of the 110 ocean layers is assigned an ocean sediment section. Ocean layer and sediment sector widths are determined from observed ocean depth distributions.

The DCESS Earth System Model can be downloaded from the link below. The programs have been extensively tested and should work well for Matlab version 7.0 or higher. DCESS has very limited human resources and can not provide support for users downloading these programs. However the programs are sufficiently straightforward and sufficiently well documented for users with reasonable Matlab skills to find their way through them and to adapt them for their particular applications.
