A selection of several GOES ABI loops during 2022 and 2023 showcased the diverse range of features observed, which included volcanic ash plumes, hurricanes, convection, fog, smoke, fires, dust and ice. It’s very hard to choose just one event from every month of the year, but the goal here is to show a variety of phenomena and locations that... Read More

The ATS was followed by the SMS, which carried an early version of the VISSR.To prepare for the 50th anniversary of GOES,... Read More

Cold air over the Great Lakes (see the plot of 850-mb temperature from RAOB stations at 1200 UTC below; note the similarity in temperatures and wind speeds over the Great Lakes states) means Lake Effect Snow. The animation above (source) shows snow bands over western lower Michigan and also downwind... Read More
