GLI atmospheric correction algorithms: performance test with GLI synthetic data set

Two types of algorithm selected for ADEOS-II/GLI atmospheric correction for ocean applications were summarized. The standard algorithm, OTSK1a, is an extension from the OCTS algorithm (and also similar to current SeaWiFS/MODIS algorithm). The research algorithm, OTSK1b, is selected to validate OTSK1a. OTSK1b is a new approach for atmospheric correction by using multi-layered perceptrons (i.e. neural network) to model the transfer function between top-of- atmosphere GLI reflectances and above-surface marine reflectances. The performance of these two algorithms was tested with GLI synthetic dataset and MODIS data.
