Comparison of GOES-R ABI with current GOES Imager
ABI Current Spectral Coverage 16 bands 5 bands Spatial resolution 0.64 mm Visible km Approx. 1 km Other Visible/nearIR km n/a Bands (>2 mm) 2 km Approx. 4 km Spatial coverage Full disk per hour Every 3 hours CONUS per hour ~4 per hour Visible On-orbit calibration Yes No Low-light imaging Yes No

Energy emitted from Earth plus atmosphere to satellite
Energy emitted from sun, reflected from Earth plus atmosphere to satellite Energy emitted from Earth plus atmosphere to satellite Human vision 2.25µm 3.9µm 10.35µm 11.2µm GOES-R 3.9µm 10.7µm Current GOES

Synthetic Fire Imagery
Acquire WF_ABBA retrieved fires and use the lat/lon to position fire hotspots within model domain. Run simulated atmosphere with fire hotspots through SHDOMPP to produce synthetic 2.25 µm and 3.9 µm imagery. Imagery produced every five minutes to match GOES-R. This is done on a grid with 400 m horizontal grid spacings. Apply appropriate GOES-R ABI point spread function on 400 m data to “build” appropriate GOES-R footprint.

Thank You! Collaborations
Synthetic GOES-R ABI imagery at 3.9, 10.35, and 11.2 µm is being used at to aid in the development of WF_ABBA a fire detection and retrieval algorithm. (CIMSS: Jay Hoffman, Chris Schmidt) Synthetic GOES-R ABI imagery may be used to aid in development of algorithms aimed at emissions from fires and retrievals of optical depths of smoke. (NOAA/NESDIS: Shobha Kondragunta, Xiaoyang Zhang) Additional collaborations are welcome! Feel free to pass along a comment and/or idea. Thank You!
