GOES-West Mesoscale view - Band 12 at 19°S - 174°W - Near Tonga*

About Band 12

9.6 µm - "Ozone" Band - 2 km resolution - Band 12 will provide information both day and night about the dynamics of the atmosphere near the tropopause with high spatial and temporal resolutions. For clear (cloud-free) scenes of view, this band is cooler than the IR window bands because of absorption due to ozone.

*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.
