A Closer Look at the ABI on the GOES-R Series (Bulletin of the American Meteorological Society):
The GOES-R Program encountered a performance issue with the cooling system of the GOES-17 Advanced Baseline Imager (ABI) instrument during post-launch checkout in 2018. The loop heat pipe (LHP) subsystem, which transfers heat from the ABI electronics to the radiator, is not operating at its designed capacity. This is preventing adequate cooling for some of the infrared (IR) channels on the instrument. The effect is worse during warm portions of orbit, near midnight when sun enters the ABI aperture, and during warm seasons around vernal and autumnal equinoxes. Under worst case conditions, local emission and dark current noise cause the longer wavelength channels saturate and become unusable for some hours.
Optimization techniques have been successful in recovering more than 97% of planned ABI data. GOES-17 is currently observing with more channels, at a higher resolution, and with more rapid refresh than what is available from the current GOES West satellite. NOAA is confident the GOES constellation will continue to meet the operational needs of the National Weather Service and forecasters across the nation. See the GOES-17 ABI Performance webpage for additional information.
