Evaluation of the GOES 1-M Normalization Technique with the Visible Images of GOES-7
Abstract
The visible images of the earth from the current and future NOAA geostationary satellites are produced from observations by eight separate detectors. Because the detectors have different responses to the reflected solar energy and are not calibrated in flight, the signals from seven of the detectors are normalized to that of the eighth detector to avoid banding or striping the images. A technique employing matching of the channels' empirical distribution functions has been proposed for minimizing the striping in the images from the future GOES I-M spacecraft. This method has been evaluated in an operational setting with the data of GOES 7. The results from a series of comparisons between the images derived from the operational normalization technique and the new technique are discussed quantitatively. The new technique significantly reduces the level of striping in the visible images compared to that produced by the operational procedures. The new method improved the image quality to an extent that warranted its implementation for the GOES 7 operational images in June 1989.
