GOES-18 became the operational GOES-West satellite at 1800 UTC on 4 January. The toggle above shows the GOES-West (labeled as GOES-17, but the 1806 UTC image is using GOES-18 satellite information) IFR Probability Fields before/after the changeover. The IFR Probability field gives more useful information about surface visibility/ceiling restrictions than (for example) visible imagery (shown here) that shows widespread cloudiness at the...

It’s very hard to choose just one event from every month of the year, but the goal is to show the range of phenomena and locations that NOAA‘s GOES ABI routinely monitors, in this case during 2022. Most loops generated are from the University of Wisconsin-Madison CIMSS Satellite Blog, which... Read More

GOES-16 (GOES-East) Nighttime Microphysics RGB and Day Snow-Fog RGB images (above) showed a lake effect fog/stratus plume that was meandering slowly northward from the still-unfrozen Fort Peck Lake in northeastern Montana (just south of Glasgow) on 08 December 2022.During the hours leading up to sunrise, GOES-16 Nighttime Microphysics RGB images with an overlay of the GOES-16 Cloud Top Phase derived...

GOES-16 IFR Probability fields, shown above, (click here for a slower animation) combine satellite information about low clouds with Rapid Refresh model estimates of low-level saturation. On this day, regions of observed IFR conditions (that is, ceiling less than 1000 feet and/or visibilities less than 3 statute miles) are apparent over south-central Lower Michigan, northeast...
