In order to get 8 images per hour over the CONUS, what is changed in the scan schedule? Differences for GOES West: the southern hemisphere sector is smaller and there is an additional smaller CONUS sector called the subconus sector. If you are along the west coast, you will notice that these subconus sectors are resopnsible for the cropped images over the Pacific during an RSO. Differences for GOES East: there is no Extended Northern Hemisphere sector and there is a much abreviated southern hemisphere sector. When there is a rapid scan, most of the Southern hemisphere/South America only gets imaged every 3 hours (during the Full Disk scan).
