GOES-19 Advanced Baseline Imager (ABI) Post Launch Test Performance and Comparison to GOES-16, GOES-17, and GOES-18

The 19^th Geostationary Operational Environmental Satellite (GOES-19) will be taking over the GOES-East slot in 2025 as the 4^th and final U.S. geostationary weather satellite of the GOES-R series, with GOES-16 transitioning to the role of on-orbit spare. The Advanced Baseline Imager (ABI) is the primary instrument on the GOES-R series for weather and environmental monitoring. With three times the spectral bands, four times the spatial resolution, and five times the image collection rate of previous generation instruments, ABI significantly improves the quality and frequency of existing data products and provides many new weather and environmental products.

The GOES-16 ABI (Flight Model 1), currently active as GOES-East, has already demonstrated these improvements during more than 7 years of on-orbit operations. This paper describes preliminary results from the GOES-19 ABI (Flight Model 4) post launch test campaign and compares observed performance to GOES-16, GOES-17, and GOES-18 ABI.
