The next generation geostationary satellite series will offer a continuation of current products and services and enable improved and new capabilities. The Advanced Baseline Imager (ABI) on the Geostationary Operational Environmental Satellites (GOES)-R series will monitor a wide range of phenomena. As with the current GOES Imager, the ABI will be used for weather, oceanographic, climate, and environmental applications. The ABI will improve upon the current GOES Imager with more spectral bands, faster imaging, higher spatial resolution, better navigation, and more accurate calibration. The ABI expands from five spectral bands on the current GOES imagers to a total of 16 spectral bands in the visible (2), near-infrared (4) and infrared (10) spectral regions. There will be an increase of the coverage rate leading to full disk scans at least every 15 minutes and continental US (CONUS) scans every 5 minutes. High-time resolution loops over mesoscale regions will also be possible. Sample high-temporal resolution GOES-14 and GOES-15 imager data from their post-launch check-outs will be shown, along with outlining various possible ABI scan scenarios. ABI spatial resolution (at the satellite sub-point) will be nominally 2 km for the infrared bands and 0.5 km for the 0.64 micrometer visible band. High-quality simulated data, as well as other satellite observations, are being used in a number of ways to prepare for the ABI information.
