Abstract

Shortly after launch, vertical stripes were found in the 3.9 μm channel images of the Advanced Baseline Imager (ABI) on GOES-18. This has been called “Barcode Artifact” (BA) because it is a non-natural phenomenon similar to the barcode found in supermarkets. While BA was initially discovered and monitored qualitatively and subjectively by human inspection, that is not suitable for examining large number of images to characterize BA’s potential dependence on channel, flight module, background signal intensity, time of the day, season of the year, etc., and in particular to evaluate BA’s response to various mitigation measures. We designed three automated methods to quantify BA objectively, tested their effectiveness in practice, and recommend possible future improvement for GOES-19 and the next generation GeoXO Imager (GXI).

Quantification of Barcode Artifact

Shortly after launch, vertical stripes were found in the 3.9 μm channel images of the Advanced Baseline Imager (ABI) on GOES-18. This has been called “Barcode Artifact” (BA) because it is a non-natural phenomenon similar to the barcode found in supermarkets. While BA was initially discovered and monitored qualitatively and subjectively by human inspection, that is not suitable for examining large number of images to characterize BA’s potential dependence on channel, flight module, background signal intensity, time of the day, season of the year, etc., and in particular to evaluate BA’s response to various mitigation measures. We designed three automated methods to quantify BA objectively, tested their effectiveness in practice, and recommend possible future improvement for GOES-19 and the next generation GeoXO Imager (GXI).
