Stereoscopic views of severe convection over Nebraska

Strong convection developed over Nebraska late in the afternoon of June 8th (SPC Storm reports are here).  Mesoscale domains from both GOES-16 and GOES-17 viewed this developing convection, enabling fine spatial and temporal-scale viewing of the convection.  (Past Mesoscale domain sectors can be searched at this website; this website shows locations in the past year.)

The stereoscopic mp4 animation (created using geo2grid and ffmpeg;  a similar blog post on this technique is here) above captures the convective development near 2200 UTC on the 8th, and follows the storm evolution through sunset.  To view the imagery in three dimensions, cross your eyes until three images are present, and focus on the image in the middle.

A 2-panel comparison of GOES-17 and GOES-16 Visible images during the period 2230-0208 UTC is shown below, with time-matched plots of SPC Storm Reports. The images are displayed in the native projection of each satellite.
