  11. 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.

  25. 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

  40. GOES-R The great amount of information from the GOES-R series will both offer a continuation of current product and services, but also allow for improved or new capabilities. These products, based on validated requirements, will cover a wide range of phenomena. This includes applications relating to: weather, ocean, coastal zones, land, hazards, solar and space. The Advanced Baseline Imager (ABI), the Hyperspectral Environmental Suite (HES), the Geostationary Lightning Mapper (GLM), the space and solar instrument suites (Solar Imaging Suite (SIS) and the Space Environment In-Situ Suite (SEISS) on GOES-R will enable much improved monitoring compared to current capabilities.
