Recently, GOES-18 observed a number of weather events, environmental phenomena, and striking views of our planet. Storms across east Texas produced large hail, strong wind gusts, and tornadoes. Farther west in New Mexico, strong winds resulted in large areas of blowing dust and expansion of large wildfires. Fog blanketed parts of Chile in South America, and clouds and some thunderstorms formed along sea breezes in the Yucatan and south Florida.
GOES-18 is currently undergoing post-launch testing, validation and calibration of its instruments and systems to prepare it for operations. The ABI cooling system is performing well, with no signs of the issue that affects its sister satellite, GOES-17. The ABI was redesigned for GOES-18 to reduce the likelihood of future cooling system anomalies. The new design uses a simpler hardware configuration that eliminates the filters that are susceptible to debris.
GOES-18 will assist GOES-17 with GOES West operations in late summer 2022 and again in early fall. NOAA plans for GOES-18 to replace GOES-17 as GOES West in early 2023. Imagery from GOES-18 during the post-launch testing phase should be considered preliminary and non-operational.
