Abstract:
The Advanced Baseline Imager (ABI) on the Geostationary Operational Environmental Satellite (GOES)-R Series is a greatly improved instrument compared to the legacy GOES imager. With 3 times more spectral bands, improved spatial resolution, and more frequent imagery the ABI has proven to be a critical asset for the National Weather Service and others. With two ABIs in orbit on GOES-East and GOES-West, the majority of the images generated are free of visual defects, well calibrated, and produced in a timely fashion. Yet, visual artifacts, or anomalies, still occur. This presentation lists and explains a number of the most common artifacts, some of which are traditional imagery defects for imagers such as striping and stray light, and more colorfully named artifacts such as “caterpillar tracks” and “shark fins.” Multiple resources will be presented for users to obtain more information about image quality and near-real-time image monitoring.
