The offline, zero dimensional version of the Simplified Biosphere (SSiB) midel has been implemented in a global, two dimensional framework. This version allows global simulation of hydrologic and energy flux terms at the land surface driven by gridded meteorological data (observed or analyzed). It is intended for use as a tool for land surface data assimilation and model development. It has the advantages of being much less expensive to execute than SSiB couple to an atmospheric model, and, lacking feedbacks with the free atmosphere, it is easier to diagnose. These features make it ideal for sensitivity testing over large areas.
The history and framework of the SSiB model in general and its two dimensional implementation are explained, and a brief tutorial is presented.
