GOES-18 data in this post are preliminary and non-operational and beautiful. Because GOES-18 and GOES-16 nadir positions are separated by almost 15o of longitude (89.5o and 75.2o, respectively), they can be used (when remapped to the same projection, in this case using a beta version of geo2grid that supports GOES-18...

1-minute Mesoscale Domain Sector GOES-17 (GOES-West) “Clean” Infrared Window (10.35 µm) images (above) showed thunderstorms associated with the South Pacific Convergence Zone (SPCZ) on 21 February 2021. The 3 METAR stations plotted on the imagery are, from left to right, Hihifo Airport, Wallis and Fotuna (NLWW), Apia, Samoa (NSFA) and Pago Pago, American Samoa (NSTU).In spite... Read More
GOES-17 is typically operational using Mode 3 Scanning, in which mode Full Disk images are acquired every 15 minutes (in addition to a PACUS sector every 5 minutes and two mesoscale sectors every minute). NOAA/NESDIS plans a transition to operational Mode 6 scanning at some point in Spring, and testing... Read More
GOES-15 (GOES-West) Visible (0.63 µm) and GOES-16 (GOES-East) “Red” Visible (0.64 µm) images — displayed in the native projection of each satellite, and centered on Las Vegas, Nevada — are shown above, depicting the development of deep convection across parts of the Desert Southwest on 12 July 2018. While the GOES-15 satellite... Read More
