Albedo is essential in earth radiation budget and global climate monitoring. GLASS albedo is a newly developed global broadband land-surface albedo product with 1-km spatial resolution and 1-day temporal resolution. AB algorithm is employed to generate daily albedo product by building a linear regression relationship between narrowband directional reflectance and broadband albedo. AB algorithm avoids the restrictions on the observing angles, but suffers from the assumption that the land surface should be homogeneous and flat without terrain relief. In our research, we proposed a technique to improve AB algorithm for retrieving albedo in rugged terrain, which is called tab algorithm. The preliminary validation using simulation data indicated that the accuracy of AB algorithm could be significantly improved when the terrain effect is considered.

The paper designed a hybrid improved Particle Swarm algorithm for Constrained Optimization,a solution of an advanced fitness function,which introduced the conception of feasible zone to treat with the restrained ***,the writer adopted the outer of set to preserve the non-dominated set just found,and joined tab algorithm in selecting of the optimal value of the best,so that it avoided getting into the optimizing locality earlier and improved the solution *** experiments indicated that this algorithm can solve the constraint multi-objective optimum problems,and it is a most potential multiobjective optimal approaches.
