In this talk, we will present different algorithms for estimating a series of land surface variables and the preliminary results from two EO-1 sensors: ALI (advanced land imager) and Hyperion. These variables include spectral reflectance from the atmospheric correction algorithms, broadband albedos converted from narrowband albedos, and leaf area index. The validation results based on the ground measurements from the field campaigns at both Beltsville, Maryland and Coleambally, Australia will be shown. ALI corresponds to Landsat7/ETM+ sensor, its advantages for estimating these land surface variables over ETM+ will be demonstrated.
