GOES-13 Infrared Window (10.7 um) images [click to enlarge]

GOES-13 Infrared Window (10.7 um) images, above, showed Otto around the time that is became the latest hurricane on record to form in the Caribbean Sea on 22 November (NHC advisory).

A comparison of GOES-13 Visible (0.63 um) and Infrared Window (10.7 um) images, below, revealed multiple convective bursts which exhibited IR brightness temperatures of -80 C and colder (violet enhancement). Because of Otto’s central dense overcast no eye was apparent in the GOES-13 imagery; even on a DMSP-16 SSMIS Microwave (85 GHz) image at 2049 UTC the eyewall was not fully closed.
