Testing of GOES-16 and GOES-17 Mode 6 scan strategy
Both GOES-16 (GOES-East) and GOES-17 (GOES-West) were placed into the Mode 6 scan strategy for a 3-day period of testing beginning at 1500 UTC on 19 February 2019 — which provides Full Disk images every 10 minutes (instead of every 15 minutes for the more common Mode 3 scan strategy). Further details on GOES-R series scan modes are available here and here. GOES-16 Full Disk “Red” Visible (0.64 µm) images are shown above, with Mid-level Water Vapor (6.9 µm) images below. One of the more striking features over the North Atlantic Ocean was a rapidly-intensifying Hurricane Force low — an animation that cycles through GOES-16 Visible and Water Vapor images of this system is displayed below. GOES-16 Air Mass RGB images from the AOS site (below) exhibited the orange-to-red hues of ozone-rich air within the atmospheric column due to a lowered tropopause associated with the rapidly deepening North Atlantic storm.![GOES-16 Air Mass RGB images [click to play animation | MP4]](https://cimss.ssec.wisc.edu/satellite-blog/wp-content/uploads/sites/5/2019/02/20190219213016_fulldisk.jpg)
