Advanced Baseline Imager
From Glossary of Meteorology
(Abbreviated ABI.) ABI is a 16 channel high-resolution imaging radiometer being designed for the GOES-R series of satellites covering visible, short, mid- and long-wavelength infrared spectral regions. The visible and near-infrared channels will provide 500 m (one channel only) or 1 km resolution imagery at nadir, while the remaining infrared channels will have a nadir resolution of 2 km.
