  13. While there are differences, there are also many similarities for the spectral bands on MET-8 and the Advanced Baseline Imager (ABI). Both the MET-8 and ABI have many more bands than the current operational imagers.

  14. Three-color composite (0.64, 1.6 and 11 µm) shows the low cloud over the snow and the water versus ice clouds. Snow Low cloud

  18. Mountain Waves in WV channel (6.7 µm) 7 April 2000, 1815 UTC Simulated ABI Actual GOES-8 Mountain waves over Colorado and New Mexico were induced by strong northwesterly flow associated with a pair of upper-tropospheric jet streaks moving across the elevated terrain of the southern and central Rocky Mountains. The mountain waves appear more well-defined over Colorado; in fact, several aircraft reported moderate to severe turbulence over that region. Both images are shown in GOES projection. UW/CIMSS

  28. Current GOES scans 5 times slower than the ABI There are two anticipated scan modes for the ABI: - Full disk images every 15 minutes + CONUS images every 5 minutes + mesoscale. or - Full disk every 5 minutes.

  29. ABI can offer Continental US images every 5 minutes for routine monitoring of a wide range of events (storms, dust, volcanoes, fires, hurricanes, etc). This is only every 15 or 30 minutes with the current GOES the routine mode.

  30. “Franklin” Mesoscale images every 30 seconds for rapidly changing phenomena (thunderstorms, hurricanes, fires, etc). Current GOES can not offer these rapid scans while still scanning other important regions

  31. Draft GOES-R 3-hour schedule for the ABI MSS = Mesoscale Scans from the ABI CONUS = Continental US FD = Full imaging disk scan This is a combination of mode 3 (“Flex” and mode 4 “Continuous Full Disk”).

  32. Fixed Grid Format • The distributed, calibrated and navigationally corrected image data will be rectified [re-grid] to a fixed grid. The grid is defined relative to an ideal geostationary satellite viewpoint centered and fixed above the equator. The image pixels will have an angular separation in both the East/West and North/South directions of: • 14 microradians (0.5 km) in the 0.64 micron channel, • 28 microradians (1 km) in the 0.47, 0.86 and 1.61 um channel, • 56 microradians (2 km) in all other channels.

  33. Summary The great amount of information from the GOES-R ABI will offer a continuation of current products and services. These products, based on validated requirements, will cover a wide range of phenomena. This includes applications relating to: weather, ocean, land, climate, and hazards. The ABI improves over the current GOES Imager the spectral, temporal, spatial and radiometric performance. The Advanced Baseline Imager (ABI), along with the Hyperspectral Environmental Suite (HES), and the Geostationary Lightning Mapper (GLM) on GOES-R will enable much improved monitoring compared to current capabilities.
