| Abstract | Based on the water-leaving multi-spectral radiance from the ocean water, the 3D chlorophyll concentration is reconstructed. The inverse problem is formulated as an optimization problem and iteratively solved by the meta-heuristics Ant Colony Optimization, using the radiative transfer equation as direct model. An objective function is given by the square difference between computed and experimental radiance at every iteration. It was included an intrinsic regularization scheme that pre-selects candidate solutions at every iteration based on their smoothness, quantified by the 2nd order Tikhonov norm. Additional information is also used to compute the inverse solution: the concavity of the chlorophyll profile that is verified by means of its second derivative. In the higher depths a additional step was necessary to improve the reconstruction, since it is usually obtained poor results in this region for most of the profiles, since we are considering only data of raciances measured above the water. For considering an ocean surface divided in several sub-domains (as pixels in an image), there will be a significant amount of computation to be performed. The demand for high processing power is addressed with the use of grid computing to speed up the inversion process. A grid infrastructure with three clusters geographically distributed was built to perform the inversion for each pixel. | |||
