* GOES-17 imagery posted here is preliminary and non-operational *

A composite of GOES-17 and GOES-16 True Color Red-Green-Blue (RGB) imagery (above) was created by blending a total of 59 north-south swaths — each swath within +/- 23 minutes of “local Noon” (for example, the blue swaths using GOES-16) — during the period beginning at 1115 UTC on 26 November (over the eastern Atlantic Ocean and far western Africa, using GOES-16) and ending at 0200 UTC on 27 November 2018 (over the western Pacific Ocean, using GOES-17). Since the GOES-16/17 ABI does not have a true “Green” (0.51 ┬Ám) spectral band, that component of the RGB image is simulated using other Near-Infrared bands.

For perspective, the GOES-17/GOES-16 True Color composite is overlaid on a global “Blue Marble” background (below), which helps to emphasize the total areal coverage provided by the GOES-R constellation.

Notable Northern Hemisphere features seen in the imagery include (1) a pair of strong mid-latitude cyclones in the North Atlantic, (2) a large storm in the Gulf of Alaska with a trailing cold front moving inland along the west coast of North America, (3) two storms in the West Pacific, and (4) convective cloud bands along the Intertropical Convergence Zone (ITCZ) in the tropical Atlantic and Pacific basins (below).

Kudos to Rick Kohrs (SSEC) for masterfully perfecting the blending technique to create these composite GOES images.
