Advanced Baseline Imager (ABI)

The Advanced Baseline Imager is the primary instrument on the GOES-R Series for imaging Earth’s weather, oceans and environment. ABI views the Earth with 16 different spectral bands (compared to five on the previous generation of GOES), including two visible channels, four near-infrared channels, and ten infrared channels.

It provides three times more spectral information, four times the spatial resolution, and more than five times faster temporal coverage than the previous system.

ABI is a mission critical payload for the GOES-R Series, providing more than 65 percent of all mission data products currently defined.

ABI is a multi-channel passive imaging radiometer designed to observe the Western Hemisphere and provide variable area imagery and radiometric information of Earth’s surface, atmosphere and cloud cover. The instrument has two scan modes. The default mode concurrently takes a full disk (Western Hemisphere) image every 15 minutes, an image of the Continental U.S. every five minutes, and two smaller, more detailed images of areas where storm activity is present, every 60 seconds. The ABI can also operate in continuous full disk mode, providing uninterrupted scans of the full disk every 5 minutes. All ABI bands have on-orbit calibration.

ABI is used for a wide range of applications related to weather, oceans, land, climate and hazards (fires, volcanoes, floods, hurricanes and storms that spawn tornadoes).

ABI improves every product from the previous GOES imager and introduces a host of new products.

It tracks and monitors cloud formation, atmospheric motion, convection, land surface temperature, ocean dynamics, flow of water, fire, smoke, volcanic ash plumes, aerosols and air quality, and vegetative health. ABI’s data enables meteorologists to pinpoint and track developing storms in much greater detail. Future products will also help the aviation industry with aircraft icing threat detection and turbulent flight condition predictions.

Benefits from the ABI include improved tropical cyclone forecasts, fewer weather-related flight delays and airline incidences with volcanic plumes, improved production and distribution of electricity and natural gas, increased efficiency in irrigated water usage in agriculture, and higher protection rates for recreational boats in the event of a tropical storm or hurricane.


  • Full Disk: Hemispheric Coverage of 83° local zenith angle, temporal resolution of 5-15 minutes, and spatial resolution of 0.5 to 2km
  • Mesoscale: Provides coverage over a 1000x1000km box with a temporal resolution of 30 seconds, and spatial resolution of 0.5 to 2km.
  • Continental US: The CONUS scan is performed every 5 minutes, providing coverage of the 5000km (E/W) and 3000km (N/S) rectangle over the United States. The spatial resolution is 0.5 to 2km.
  • Flex Mode: The flex mode provides a full disk scan every 15 minutes, a CONUS every 5 minutes, and two mesoscale every 60 seconds (or one sub-region every 30 seconds).

One-minute infrared imagery of the powerful storm system that brought hail and tornadoes to the Southeastern U.S. on April 5, 2017. This imagery was produced with the “longwave” infrared band on the GOES-ABI, a new band not available on the previous generation of GOES. The one-minute scanning is also a new capability on GOES-16. As seen here, the imagery produced by this band offers spectacular views of meteorological phenomena, such as the colder cloud tops (shown in green/yellow/red) associated with these storms, in rich detail. Of particular note are what's known as "enhanced-V features" on some of the cloud tops, which are indicative of severe storm formation.
