Both Hurricanes <\/a>Charley<\/a> (2004) and Ian<\/a> (2022) were extremely strong storms to strike the west coast of Florida. Both Charley<\/a> and Ian were upper Category 4 storms, as a measure of their wind speeds. Of course wind speed is only one of the critical impacts of a hurricane. For more information on Hurricane Ian, see other UW CIMSS Satellite Blog<\/a> posts such as when the hurricane made a landfall in Florida on September 28th<\/a> and again in South Carolina on the 30th<\/a> (by Scott Bachmeier<\/a>, UW\/CIMSS<\/a>), the CIMSS Tropical Cyclones page<\/a>, or a blog post by Bill Line,<\/a> NOAA \/ NEDSIS.<\/p>\n\n\n\n

GOES-12 versus GOES-16 (ABI)<\/h2>\n\n\n\n

The quality of the monitoring of storms between GOES-12 and GOES-16 were orders of magnitude improved. For example, GOES-12 provided imagery with intervals of between 7 and 30 minutes, while the Advanced Baseline Imager<\/a> (ABI) provided images every 30 seconds via the meso-scale sector. The spatial resolutions of the longwave infrared window improved from approximately 4 to 2 km, while the visible band improved from 1 to 0.5 km. In addition, there were calibration and navigation improvements. <\/p>\n\n\n\n

Longwave Infrared band<\/h4>\n\n\n\n

This longwave infrared window (heat of the emitting surface) loop has the imagery remapped to the same projection. The Ian ABI loop runs from 13:00:28 to 17:59:55 UTC on September 29, 2022, while the GOES-12 Imager Charley loop covers from 15:15 to 19:55 UTC on August 13, 2004. Note the improved temporal and spatial resolutions. <\/p>\n\n\n\n

There were several social media posts comparing these two storms, both the satellite and radar perspectives.<\/p>\n\n\n\n
