- Tornado Alley (50 MB MOV) 26 May - 01 June 2013 .
GOES-14 provided this imagery from its parking orbit at 105W, while GOES-13 recovered at 75W from a meteorite strike.
The last week of May experienced daily tornado outbreaks throughout the Midwest, fueled by moisture streaming northward out of the Gulf and heated by a strong dose of early summer sun.
On Friday, May 31, three Discovery Channel "storm chasers" in central Oklahoma were killed by a multiple-vortex storm, and three other "storm chasers" from the Weather Channel were shaken up when a tornado tossed their SUV 200 yards.
- For experimental animations of Sandy taken at few-minute intervals by GOES-14 parked at 90W, visit the CIMMS library of super-rapid-scan pictures at the University of Wisconsin, such as the 6-day epic 507 MB movie sandy_daytime_epic_NOAA.mov.

- Paul and Rafael (0.5 MB JPG) at 2345 UTC on 14 October 2012.
The two storms in the subtropical Pacific and Atlantic make nice "earings" to North America, complemented by a "necklace" of clouds across the entire Inter-Tropical Convergence Zone (ITCZ) in the western hemisphere.
- West Texas Fog Ring (0.3 MB JPG) at 1430 UTC on 4 October 2012.
The dawn view of the South in early autumn reveals patches of fog from the Appalachian valleys to the High Plains, particularly a filigreed fog ring surrounding the great mesa in West Texas and eastern New Mexico known as the "Llano Estacado", an arid slab the size of Indiana.
- Full disk at 105W (1.5 MB JPG) at 1745 UTC on 1 October 2012.
When GOES-13 was suddenly taken offline as GOES-EAST at 75W, GOES-14 was pressed into service from its storage location at 105W, providing a rare operational view of the fulldisk from mid-continent.
- Tropical Storm Danny rapid scans from GOES-14 (8.4 MB MP4) 26 August 2009.
During post-launch checkout, GOES-14 once again took rapid scans in hurricane alley, watching the storm try, but fail, to become a hurricane.
The visible images are presented at one-quarter resolution (4 km).
- Hurricane Bill rapid scans from GOES-14 in visible, dawn-to-dusk (10.8 MB MP4) 1000-2300 UTC 21 August 2009.
The second day of rapid scans at full-resolution visible is less dramatic, as the eye is not so well-formed.
This day's movie is much more digitally compressed by the H.264 codec.
- Hurricane Bill rapid scans from GOES-14 in visible, dawn-to-dusk (40.9 MB MOV) 1000-2200 UTC on 20 August 2009.
This large movie is a full-resolution view of the storm in the GOES-14 visible channel. The mid-afternoon development is missing because post-launch engineering tests took precedence.
- Hurricane Bill rapid scans from GOES-14 in infrared (23 MB MOV) 20-21 August 2009.
The movie is a full-resolution view in the 11 micron infrared band for a-day-and-a-half. There are occasional brightness flickers and "camera shakes" because calibration and image navigation have not yet been established.
- Hurricane Bill rapid scans from GOES-14 in visible, dawn-to-noon (20.9 MB MOV) 1000-1500 UTC on 20 August 2009.
GOES-14 made rapid scans of Hurricane Bill in mid-Atlantic.
This movie is full-resolution visible, from local dawn to noon, as the eye of the storm opens.
- Hurricane Bill rapid scans from GOES-14 in the infrared (6.1 MB MOV) 0100-1500 UTC on 20 August 2009.
During the early days of post-launch engineering tests, the Imager was used to scan Hurricane Bill in the mid-Atlantic continuously at more-or-less 5 minute intervals.
This movie is a low-resolution view in the infrared 11 micron band, mostly in the dark of night.
First full-disk infrared images from GOES-14, at 1730 UTC on 17 August 2009.
The satellite and instrument performed well.
However, the ground system had problems writing the new rebroadcast format for channels 3 and 6, where the right-hand side of the image was partly over-written with the left-hand side.
The post-launch checkout is performed to discover and fix such problems.
GOES-14 took a full-disk image of the Earth during sub-satellite noon at 90W during a mid-summer heat wave in the eastern USA. Hurricane Bill appears far to the east of the Caribbean Sea. The picture is composed of data from visible and two infrared "window" channels placed in color layers of a digital image. Yellow clouds correspond to bright, low (warm) layers, such as the marine stratus southwest of California. Blue clouds are dark, high, cold layers, such as the great winter storms in the southern hemisphere. White clouds are both high (cold) and well illuminated by the sun, such as the string of thunderstorms over the tropics in the Pacific. The deep blue tint of the oceans and the brown tint of the continents result from the differences in temperature and reflectance from water and land. The colorful result illustrates the wide range of weather and climate that occurs simultaneously over the globe.
