Abstract
The 18th Geostationary Operational Environmental Satellite (GOES-18) was launched on 1 March 2022 and became operational on 4 January 2023, replacing GOES-17 as GOES-West. For GOES-18 ABI, the solar channel calibration has a large seasonal variation, even after the correction of an alignment parameter. This paper reports a method to correct these errors, which is similar to the method proposed for GOES-16/17 ABI. We will report the results for GOES-18 and an update for GOES-16/17. The method and the corrected calibration coefficients can be used in a reprocessing of the ABI L0 data.
