As part of the GOES-15 Post Launch Science Test<\/a><\/strong>, the satellite was placed into Super Rapid Scan Operations (SRSO) mode on 13 September 2010<\/strong><\/a>, providing images as frequently as every 1 minute during the day. GOES-15 0.63 \u00c2\u00b5m visible channel images (above; also available as a QuickTime movie<\/a>)<\/em><\/strong> showed the well-defined eye of Hurricane Igor, with SRSO images during a 4 hour period (from 16:39 – 20:39 UTC)<\/em>. The visible images were brightened a bit after 19:26 UTC to help detect the presence of any mesoscale vortices within the eye.<\/p>\n

A comparison of 1-minute interval GOES-15 SRSO images with the normal operational 15-minute interval GOES-13 visible images (below)<\/em><\/strong> clearly demonstrates the advantage of higher temporal resolution for monitoring the evolution of the eye structure of the hurricane (courtesy of Tim Schmit, NOAA\/ASPB<\/a>)<\/em>.<\/p>\n

While Hurricane Igor maintained a Category 4 intensity for more than 24 hours, an SSMI\/S 85 GHz microwave brightness temperature image from the CIMSS Tropical Cyclones<\/a><\/strong> site (below)<\/em><\/strong> suggested that the storm might be entering an eyewall replacement cycle (ERC) late in the day on 13 September, which would signal a likely decrease of the storm’s intensity during the ERC process.<\/p>\n
