Note the differences in parallax<\/a><\/strong> offset between the 2 satellites — a 50,000-ft cloud top feature over central Colorado would be displaced about 22 km (13.7 miles) to the northwest of its actual surface location in GOES-16<\/strong><\/a> imagery, but displaced about 23 km (14.3 miles) to the northeast of is actual surface location in GOES-18<\/strong><\/a> imagery. Parallax correction would therefore have displayed the cold overshooting top closer to the location of the 1.75-inch diameter hail report.<\/p>\n
