About Band 11
8.4 µm - "Cloud-top Phase" Band - 2 km resolution - Band 11 is used in combination with the 11.2 and 12.3 µm bands to derive cloud phase and type products. This band is similar to the "traditional" IR longwave window band, although the 8.4 µm band assists in determining the microphysical properties of clouds.
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.
