| 總結: | An atmospheric correction algorithm for the retrieval of land surface reflectance from the Medium Resolution Imaging Spectrometer (MERIS) data has been implemented. The algorithm is designed to obtain the main atmospheric parameters needed in the correction from the image itself, leading to an optimal characterization of the atmospheric state, in temporal and spatial resolution terms. The first part of this paper is devoted to the description of the method, outlining the main steps in the atmospheric characterization and in the subsequent surface reflectance retrieval. The validation task is detailed in the second part. Both the comparison of the algorithm performance with simulated data and with AERONET measurements show a high accuracy in the atmospheric and surface reflectance products. |
