Mode 4 scanning produces a full-disk image every 5 minutes.  Mesoscale sectors and CONUS sectors are not scanned (although a CONUS sector can of course be subsected out of the Full Disk image).  The mp4 animation above (from the <a href=\"https:\/\/geosphere.ssec.wisc.edu\/#playing:true;coordinate:-598098,513863;zoom:4.7;\">CSPP Geosphere site<\/a>) shows the transition. Before 1500 UTC, data are at 10-minute time-steps;  after 1500 UTC, 5-minute time-steps occurs.  Imagery is over Panama, a region where 5-minute images typically are not available.  Indeed, regions outside of GOES-16 CONUS sector will enjoy the benefits of a 5-minute cadence until 1900 UTC on 4 January 2024.  The Mode change has occurred to create simulated data for GOES-U, still scheduled for launch in late April of this year.<\/p>\n\n\n\n<p>The data feed into the National Weather Service Advanced Weather Information Processing System (AWIPS) is not greatly affected by the change from Mode 6 to Mode 4, as shown below.  Full Dis imagery changes from a 10-minute to a 5-minute cadence at 1500 UTC, and the timestamp for the CONUS sector changes from &#8230;\/1446\/1451\/1456 to 1500\/1505\/1510&#8230; UTC.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cimss.ssec.wisc.edu\/satellite-blog\/wp-content\/uploads\/sites\/5\/2024\/01\/GOES16NAtlanticBand2_Band13-20240104_1331_to_1550anim.gif\"><img loading=\"lazy\" decoding=\"async\" width=\"1339\" height=\"949\" src=\"https:\/\/cimss.ssec.wisc.edu\/satellite-blog\/wp-content\/uploads\/sites\/5\/2024\/01\/GOES16NAtlanticBand2_Band13-20240104_1331_to_1550anim.gif\" alt=\"\" class=\"wp-image-56319\"\/><\/a><figcaption class=\"wp-element-caption\">GOES-16 CONUS sector visible and Full Disk sector Band 13 infrared, 1331-1550 UTC on 4 January 2024 (Click to enlarge)<\/figcaption><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p>The &#8216;Time-Time&#8217; charts (that show scanning strategies are available online <a href=\"https:\/\/cimss.ssec.wisc.edu\/goes\/abi\/ABI_BAMS2016_Fig7_time_time_mode-4.png\">here for Mode 4<\/a> and <a href=\"https:\/\/cimss.ssec.wisc.edu\/goes\/mode6a.html\">here for Mode 6<\/a> (<a href=\"https:\/\/www.goes-r.gov\/users\/abiScanModeInfo.html\">or here<\/a>).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p>As of 1900 UTC 4 January 2024, GOES-16 is back in Mode 6 operations.
