Résumé
Soil moisture has an important effect on the partitioning of solar radiation and influences, thus, the development of weather systems. It is, therefore, expected that an improved representation of the soil moisture dynamics in atmospheric circulation models (ACM’s) will enhance their predictive skills. There are different methods to achieve this. For example, the reliability of simulated soil moisture can be improved by using more realistic model structures. Increasingly popular with the availability of more remote sensing observations is, however, to reduce the uncertainties of simulations through integration with measurements (or satellite retrievals). This thesis contributes to both aspects. Chapters 5 to 8 deal with the retrieval of soil moisture from active microwaves, whereas Chapter 9 and 10 discuss land surface model simulations performed by the Noah model. In Chapter 11, the soil moisture retrievals are compared to simulations by the Noah model coupled to the MM5 regional climate model.
