About Band 15

12.3 µm - "Dirty" Longwave IR Window Band - 2 km resolution - Band 15 at 12.3 µm offers nearly continuous monitoring for numerous applications, though usually through a split window difference with a cleaner window channel. These differences can better estimate low-level moisture, volcanic ash, airborne dust/sand, sea surface temperature, and cloud particle size.

*GOES-17 Infrared Image Quality

During post-launch testing of the GOES-17 ABI instrument, an issue with the instrument's cooling system was discovered. The loop heat pipe (LHP) subsystem, which transfers heat from the ABI electronics to the radiator, is not operating at its designed capacity. The consequence of this is that the ABI detectors cannot be maintained at their intended temperatures under certain orbital conditions. This is preventing adequate cooling for some of the infrared (IR) channels on the instrument during parts of the night, leading to partial loss of ABI imagery. Learn more.
