    Abstract:

    The data of an ocean color sensor is abnormal. There are many irregular strips in the retrieved products. Analysis of a large set of data confirms that the data abnormality mainly result from the influence of clamping (zero-voltage fluctuation) on each waveband. Thus, a method named clear water free network adjustment is put forward for repairing the clamping. Then, the clamping repair method is applied to the remote sensing image and the chlorophyll concentration is retrieved from the clamping repaired image. The retrieved products have excellent uniformity and abundant detail. Finally, the comparison between the retrieved and MODIS/Aqua product demonstrates that the clamping repaired signal is getting right, providing a new method for the study on clamping repair and support for the quantitative application of ocean color sensor.
