A sequence of GOES-16
(GOES-East) “Red” Visible (
0.64 µm), Near-Infrared “Cirrus” (
1.37 µm), Near-Infrared “Snow/Ice” (
1.61 µm), Upper-level Water Vapor (
6.2 µm), Mid-level Water Vapor (
6.9 µm), Low-level Water Vapor (
7.3 µm), “Clean” Infrared Window (
10.35 µm) and
Day Cloud Phase Distinction Red-Green-Blue (RGB) images
(above) showed both circular and linear contrails over southern Wisconsin on
31 March 2020. The circular contrail was likely created by military aircraft (Wisconsin Air National Guard) performing training operations.
A toggle between GOES-16 Visible and Cirrus images at 1601 UTC (below) indicated that the darker signature seen in Visible imagery was actually the shadow from the high-altitude contrails being cast upon the top of the low-level stratus clouds.

Another feature of interest was revealed by 1-minute
Mesoscale Domain Sector GOES-16 Visible images — a mesovortex that was moving southwestward from southwest Michigan across northwestern Indiana
(below). However, the small-scale circulation of the vortex was not captured by 1-minute GOES-16
Derived Motion Winds.
