Introducing the next generation geostationary imager-- GOES-R’s Advanced Baseline Imager (ABI)

The GOES-R notional baseline includes an Advanced Baseline Imager (ABI), a Hyperspectral Environmental Suite (HES), a lightning mapper, and advanced space and solar observing instruments. The ABI is a state of the art, 16-channel imager covering 6 visible to near-IR bands (0.47, 0.64, 0.86, 1.38, 1.61, and 2.26 um), and 10 infrared (IR) bands (3.90 um to 13.3 um). Spatial resolutions are band dependent, 0.5 km at nadir for broadband visible, 1.0 km for near IR and 2.0 km for IR. The ABI will scan the Full Disk (FD) in approximately 5 minutes.

The ABI represents an exciting expansion in geostationary remote sensing capabilities. The ABI addresses many needs by increasing spatial resolutions (to better depict a wider range of phenomena), by scanning faster (to improve temporal sampling and to scan additional regions) and by adding spectral bands (to enable new and improved products). Every product that is being produced from the current GOES Imager will be improved with data from the ABI. In additional, there will be new products to help monitoring the atmosphere, land and ocean system.

Simulated images of the ABI bands will be shown that are created from direct broadcast AIRS (Atmospheric InfraRed Sounder) and MODIS (MODerate-resolution Imaging Spectroradiometer) data received at the University of Wisconsin-Madison. The AIRS data can be used for spectral simulations of some ABI bands via convoluting mock ABI Spectral Response Functions (SRF) with the high spectral resolution data. The MODIS data can be used for spatial simulations of most ABI bands.
