GOES-15 Visible (0.63 µm) images [click to play animation]
On 15 December 2015 NOAA/NESDIS conducted a test of the new GOES-15 (GOES-West)
Rapid Scan Operations (RSO) sector for coverage of the American Samoa
region (SSD message
). GOES-15 Visible (0.63 µm, 1-km resolution)
images during the test period between 1711 and 1957 UTC are shown above, with plots of surface observations for Pago Pago (station identifier NSTU)
and Faleolo (station identifier NSFA).
Note that visible images from the Full Disk
scan at 1800 UTC and Southern Hemisphere
sectors at :22 past each hour are also included in the animation; during routine operations, there are periods when only 1 image per hour is available (from the Southern Hemisphere sector) which covers American Samoa.
The full size of the American Samoa RSO sector is shown below.

Displayed below is the American Samoa RSO sector is relation to the typical GOES-West Full Disk scan coverage.

The American Samoa RSO sector images were also successfully broadcast over the Satellite Broadcast Network (SBN) for display in AWIPS II; a sample GOES-15 Infrared (10.7 µm, 4-km resolution)
image is shown below.

As a preview to the upcoming GOES-R
series of satellites, we can examine JMA
Himawari-8 Visible (0.64 µm, 0.5 km resolution)
images for the same 3-hour time period, as seen below (sun glint over the open water is high during this time of day, due to the sun-satellite geometry of Himiwari-8 positioned at 140º East longitude). The images are available from the AHI
instrument every 10 minutes, and show the development of organized clusters of convection just north and south of the larger islands of Samoa and Apia. Remote locations such as American Samoa will receive similar images every 5 minutes from the ABI
instrument on GOES-R/S/T.
