The NESDIS GOES18 (West) animation GIF's no longer include a pre-made GIF loop for Lightning or CO2 Longwave Window. They create their site-visible Loops on the fly by including an image date and time in the script. The
HAniS-based GOES18 animations already produce all of the available image types, so why reinvent the wheel?. What this means for the future of the remaining pre-made GIF's remains to be seen, although their future may be in doubt.
A new
GOES18 GIF Loop script is up on my site's
script page. This supplants the still-partially-functional
GOES17 GIF Loop script which is no longer available because of the NESDIS GOES18 GIF animation removals and because it displays GOES18-labeled images under a GOES17 heading.
