Abstract： In order to provide more suitable surface retrieval methods, the authors reconducted forward modeling and made algorithm improvement for multiple parameters retrieval of AMSRE-E data simulated by Njoku-developed Levernberg-Marquardt iteration algorithm, and realized project code in MATLAB. The result shows that the improved retrieval method not only has somewhat higher precision than the original method but also can make retrieval of measurable roughness parameters of the exposed surface. In addition, it can attain relatively high precision in a wider water content range of vegetation.
