A toggle between time-matched Infrared images from Suomi NPP and GOES-16 (below) indicated that the coldest cloud-top infrared brightness temperature on the Suomi NP VIIRS image was -86.8ºC, compared to -81.5ºC from the GOES-16 ABI instrument (the same color enhancement has been applied to both images). The northward parallax displacement associated with GOES-16 imagery over the southern Gulf of Mexico was also apparent.
