The ABI instrument on GOES-R for provides a unique programmable scan capability in a GEO operational imager. This enables the ABI sensor to perform imaging and radiometric sampling operations rapidly over the full disk. Besides the Scan modes specified by NOAA requirements, we suggest additional scan modes and capabilities, which can offer new and unique benefits. We will examine these expected benefits for severe weather forecasting, sounding, wildfire observation, calibration/validation, etc.
