1500 UTC Full Disk images of the 16 ABI bands from GOES-17 [click to play MP4 animation]

* GOES-17 images posted here are preliminary and non-operational *

GOES-17 arrived at its GOES-West position of 137.2º W longitude on 13 November 2018, and began to transmit imagery via GOES Re-Broadcast (GRB) at 1500 UTC and the AWIPS Satellite Broadcast Network (SBN) at 1700 UTC on 15 November (NOAA/NESDIS article). Full Disk images of the 16 ABI spectral bands from GOES-17 are shown above.

Full Disk GOES-17 Low-level (7.3 µm), Mid-level (6.9 µm) and Upper-level (6.2 µm) Water Vapor images  are shown below.

The improved spatial resolution of GOES-17 (vs GOES-15) was very obvious at higher latitudes — a closer look at GOES-17 Water Vapor imagery (below) showed good detail associated with areas of low pressure in the Gulf of Alaska and the Bering Sea. Note that signatures of the higher terrain of mountain ranges across south-central and southeastern Alaska could be seen on the 7.3 µm and to a lesser extent the 6.9 µm images.

After sunrise, GOES-17 “Red” Visible (0.64 µm) images (below) provided a compelling view of the snow-covered Alaska Range (which includes Denali at 20,320 feet / 6,194 meters), the Wrangell Mountains (which includes Mt. Wrangell at 14,163 feet / 4,317 meters) and the Chugach Mountains (which includes Mount Marcus Baker, 13,176 feet / 4,016 meters). In particular, note the long shadows cast by Denali and the Alaska Range.

AWIPS images of 1-minute Mesoscale Domain Sector GOES-17 “Red” Visible (0.64 µm) and Shortwave Infrared (3.9 µm) data (below) showed the smoke and thermal anomaly (darker red pixels near the center of the images) associated with the ongoing Camp Fire in northern California.

Farther to the south in central California, a comparison of 1-minute Shortwave Infrared images from GOES-16 (GOES-East) and GOES-17 revealed differences in the size and orientation of hot pixels of the Adler/Mountaineer/Moses Fires burning in the foothills of the Sierra Nevada. These differences were due to the view angle from the 2 satellites — 62 degrees from GOES-16 over the Atlantic Ocean, vs. only 41 degrees from GOES-17 over the Pacific Ocean. There was a navigational jump with GOES-17 from 1831-1837 UTC, so those images were removed from the animation.
