GOES-16 ABI “Red Visible” (0.64 \u00b5m) from 1532-2027 UTC on 26 April 2018 (Click to enlarge)<\/p><\/div>\n

Explosions at an oil refinery in Superior WI on 26 April 2018 (news link<\/a>) produced a black plume of smoke visible in the GOES-16 “Red Visible” Band, the highest resolution (0.5 km at nadir) band on GOES-16. The plume is first visible at about 1717 UTC<\/a>, and it then streams southeastward over northwest Wisconsin. Areas immediately downwind of the refinery were evacuated due to air quality concerns.<\/p>\n

The explosion and subsequent fire was not sufficiently hot to be detected by the shortwave infrared 3.9 \u00b5m channel on GOES-16. However, the smoke plume is obvious in this animation<\/a>, cooler than the background by 3-4\u00baC, and yellow in the enhancement chosen.<\/p>\n
