GOES-16 (GOES-East) Normalized Difference Vegetation Index (NDVI) and Day Land Cloud Fire RGB images (above) revealed several hail damage swaths — which appeared as brighter shades of yellow in the NDVI images, and shades of brown in the RGB images — across parts of Nebraska and Iowa on 20 June 2022. The swaths of cropland damage were the result of wind-driven hail events that occurred on 06 June, 07 June and 14 June. One of the swaths was nearly 90 miles long (due to a series of training thunderstorms), with some swaths as wide as 10 miles in places.

Overlapping 1-minute Mesoscale Sectors provided 30-second GOES-18 Water Vapor, Near-Infrared and Shortwave Infrared images (above) that revealed thermal signatures of the SpaceX launch of the SARah-1 Mission from Vandenberg Space Force Station in California at 14:19:00 UTC on 18 June 2022.

Signatures of Falcon 9’s Stage 1 booster were seen immediately post-launch (for example, at 14:21:55 UTC, above), as well during its “entry burn” to initiate a launch site landing (at 14:26:25 UTC, below).

Of particular interest was the brief expansion of hot water vapor and CO2 produced by initiation of the Stage 1 “boostback burn” (as seen in Water Vapor and Shortwave Infrared images at 14:22:55 UTC, below).

Plume RGB images (below) provided an integrated view of the rocket booster’s hot/bright thermal signature as well as the expanding cloud of water vapor / CO2.

Kudos to Todd Beltracci, The Aerospace Corporation, for providing a heads-up on this rocket launch.
With the help of NASA, private industry and others, NOAA’s GOES-2 (as GOES-B) was launched on June 16, 1977. Similar to SMS-1/2 and GOES-1/3, there were 2 spectral bands: one visible and one longwave infrared. A still image with a map overlay is also available to provide geo-referencing for the images...

With the help of NASA, private industry and others, NOAA’s GOES-2 (as GOES-B) was launched on June 16, 1977. Similar to SMS-1/2 and GOES-1/3, there were 2 spectral bands: one visible and one longwave infrared.
The timelines show the periods when the satellites were operational. Yet, there were other times when they might have been operating. For example, when an on-orbit spacecraft comes out of storage once a year, often in August, for a routine check-out of several weeks. Another example was GOES-14, as it provided over 5 months of 1 min data (SRSOR) data to better prepare for the meso-scale sectors on the ABI. These campaigns were in 2012, 2013, 2014, 2015 and 2016. Some of these times were:

The second timeline above includes not only the U.S. GOES imagers, but also their precursors: ATS-1, 3 (including the Spin Scan Cloud Cameras) and 6 (with the 2-channel GVHRR; including an infrared band) and SMS-1/2. The GOES-R Program Office also has a more simple GOES timeline.

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched SPC Storm Reports — and showed the development severe thunderstorms across parts of Iowa, Wisconsin and Upper Michigan during the afternoon and early evening hours on 15 June 2022. Boundary layer feeder band clouds could be seen flowing north-northeastward into some of the growing thunderstorms — which produced a few tornadoes and damaging straight-line winds as strong as 80 mph in Wisconsin, and hail as large as 2.75 inches in diameter in Iowa. This convection developed along and ahead of an eastward-moving cold front (surface analyses).
In the corresponding 1-minute GOES-16 “Clean” Infrared Window (10.35 µm) images (below), pulsing overshooting tops exhibited cold infrared brightness temperatures in the -75 to -79ºC range (brighter white pixels embedded within areas of black).
