The coldest cloud-top infrared brightness temperature was -85.4\u00baC on the SNPP image, compared to -81.8\u00baC on the GOES-17 image; small-scale features such as the gravity waves propagating radially outward from the eye were seen in the higher resolution SNPP image. Note: the 0929 UTC time stamp on the SNPP image was the time that the ground station antenna began receiving the descending overpass signal – the satellite actually passed over Marie’s location at 0943 UTC<\/strong><\/a>.<\/span><\/p>\n
