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

GOES-16 (GOES-East) Red Visible (0.64 µm) images (above) revealed the development of Horizontal Convective Roll (HCR) clouds — a signature often associated with blowing snow — across parts of North Dakota, South Dakota, Minnesota and Wisconsin on 4th December 2024. Strong northwesterly winds in the wake of an arctic cold front were... Read More
GOES-19 (Preliminary/Non-operational) Day Cloud Phase Distinction RGB images (above) — created using Geo2Grid — displayed supercooled “lake effect” clouds (shades of white) streaming southeast off Lake Sakakawea in northwestern North Dakota on 25th November 2024. A smaller cloud plume was also seen streaming southeast off Devils Lake in northeastern North Dakota. Existing snow cover appeared as shades of green... Read More
