    GOES-R Series ABI Products GRABIPRD (partially restricted L1b and L2+ Data Products) - The Advanced Baseline Imager (ABI) is the primary instrument in the GOES-R Series for imaging Earth's weather, oceans, and environment. The ABI views the Earth with 16 different spectral bands compared to five on the previous generation GOES imagers. The ABI includes two visible channels, four near-infrared channels, and ten infrared channels, providing three times more spectral information, four times greater spatial resolution, and more than five times temporal coverage. This ABI data family includes the Level 1b Radiance data, Level 2 Cloud/Moisture Imagery, and several other Level 2 derived products. Product details (Readme's, maturity status) can be found at The archived products are distributed in the netCDF-4 file format with metadata attributes included.
