A Simplified Simple Biosphere Model and Its Application to Land-Atmosphere Interactions
|
Abstract:
The development of a biosphere model, Simplified Simple Biosphere Model (SSiB), and its application in climate studies are briefly described in this paper. SSiB has been validated and calibrated using many observational data. In this paper, the tests using Russian soil moisture data and HAPEX-Sahel data are presented to demonstrate the usefulness of these tests in the elucidation of the mechanisms in land surface processes and the improvement of the model. The influence of observational errors are also discussed. In land surface-atmosphere interaction studies, we mainly discuss the special interaction features in East Asia. In two East Asian studies, although the specified anomaly land forcings from the land surface were in different areas, they both had substantial impact on the summer monsoon. Finally, the application of a coupled regional atmosphere-biosphere model in prediction studies is discussed. Preliminary study indicates that this is a new area with great potential for development.
