Abstract. The large focal plane arrays used in the new generation of the Geostationary Operational Environmental Satellites (GOES) advanced baseline imager (ABI) introduce new calibration challenges compared with the heritage GOES imagers. The increased number of detectors allows for increased spatial, spectral, and temporal performance, but as a trade-off, it has an increased risk of image striping. We detail the development of a new postlaunch relative calibration capability for ABI reflective solar bands that utilizes ABI special scans to generate a set of relative gains that can be applied to improve image quality and reduce image striping. Results demonstrate that the method reduces image striping in the ABI solar reflective bands over varying scene content and time, both diurnally and over an extended period. This methodology ensures a calibration strategy that is consistent with heritage approaches yet adapts to the new postlaunch validation challenges presented by the new class of operational imagers in the GOES-R series. The developed approach is ready for operational use, as needed, and can be easily implemented into operations to support the operational production of geostationary imagery of the Earth.

使用特殊扫描的 GOES-R 系列高级基线成像仪的反射太阳带条纹缓解方法

摘要。与传统的 GOES 成像仪相比，新一代地球同步运行环境卫星 (GOES) 高级基线成像仪 (ABI) 中使用的大焦平面阵列带来了新的校准挑战。检测器数量的增加允许提高空间、光谱和时间性能，但作为权衡，它增加了图像条纹的风险。我们详细介绍了针对 ABI 反射太阳波段的新发射后相对校准功能的开发，该功能利用 ABI 特殊扫描生成一组相对增益，可用于提高图像质量并减少图像条纹。结果表明，该方法减少了 ABI 太阳反射带中在不同场景内容和时间上的图像条纹，无论是白天还是长时间。这种方法确保校准策略与传统方法一致，同时适应 GOES-R 系列中新型操作成像仪带来的新的发射后验证挑战。所开发的方法可根据需要随时投入业务使用，并可轻松实施到业务中，以支持地球静止图像的业务生产。
