This loop shows all 19 channels from the GOES-8 Sounder, at hourly intervals from 07:46 UTC on 06 April to 07:46 UTC on 07 April 1998.

• The visible channel (Channel 19) -- although in color -- does easily provide the night-day flag.
• Channels 1 and 2 show thermal gradient reversal at the tropopause.
• Only the highest clouds are evident in Channel 3; more cloud appears as one goes to the lower sensing channels (4,5,6...).
• Channels 3, 12, and 15 are all seen at about the same "altitude" (similar color range) but in different spectral regions (or "absorption bands"): Longwave CO2, Midwave H2O, Shortwave CO2.
• Relative transparency is evident across (window) Channels 6, 7, 8, 17, and 18.
• Channel 9 (ozone) is similar but different from Channel 10. Channel 12 looks much cleaner than "sibling" Channels 3 and 15; Channel 11 is even sharper looking.
• Over a long enough period (2 days), the large scale deep tropospheric thermal pattern (the "ridging" evident in Channels 3-5) can be seen to be slowly moving eastward.
