By animating daily NOAA NOAA ABI Full Disk true color imagery, how the Earth is illuminated over time can be seen. For example, how the terminator falls on the Earth until the Equinox. For details, see “What is a Solstice?” by SciJinks. Or this NOAA post. 11 UTC loops from the (northern hemisphere)... Read More

Note that the GOES-R series imagers support the generation of a true color image, given they have the blue (or 0.47 micrometer) band. Continuity is critical for operational satellites... Read More

Daily Full Disk imageryBy animating daily NOAA GOES-16 ABI Full Disk composite imagery, the year 2022 can be shown quickly. The GOES-16 loop below displays a 17 UTC image from each day of 2022 (the images are Rayleigh-corrected True Color RGB composites). This GOES-16 loop is similar to a loop... Read More
