Thanks! This was increadable to watch over and over again. I'm so used to highly compressed video, that the detail in this was staggering.

Is there a good public reasonably live feed of this data? I found the 800x800 8 bit pngs, and I found information on the restricted access full sized 103 gigabyte per day feed.

Right here: http://himawari8.nict.go.jp

How awesome would it be if we had that kind if quality available from all "sides"... (Ok, yes, one could mostly build displays of blue spheres. But fancy ones ;))
Any reason why we don't have several of these at all points?; or do we and I just do not know about it? - p.s. love the site, thank you
Europe’s weather authorities are extremely stingy with their nearest equivalent data – their attitude is that the observations are for science or for money, not for silly websites.

Feel free to provide an email address for us to complain.

Click "Credits/About" on the OP.
Fantastic! Thank you! I've cropped several as desktop wall paper.
Why not make a cron job that does that automatically every couple minutes ;)
That's the plan! It just need to be intelligent enough to find interesting lighting.
There's another satellite, DCSOVR, that takes photos of the daylight side of the earth several times a day. It's not as up-to-date as this footage, but it's always fully lit. http://epic.gsfc.nasa.gov/
Wow, DSCOVR. typo
In addition to the link posted by celoyd, you can get access to the full data stream you mentioned by filling out this application form[0].

There are also some heavily processed images from that data available from NOAA[1] - the "Geocolor Full Disk" is the best, it's half-resolution (5500x5500). The green filter on Himawari's camera doesn't correctly capture the green color of vegetation, which is why OP's video looks browner than you might expect. So this product attempts to correct for that by creating an artificial green channel made of a combination of other channels[2]. It also attempts to correct for Rayleigh scattering[3], so this is basically what the Earth would look like if the atmosphere suddenly disappeared (except for the clouds :P). The night portions of these images are a different kind of false color composite: the clouds come from two infrared channels, white are high ice clouds and red are low wet clouds; the city lights are (sadly) just a static overlay from existing data.

And (shameless plug) I've been playing with applying motion interpolation algorithms to these NOAA images to create smooth, high resolution video that can be played much slower. The Farneback optical flow algorithm[4][5] seems to work very well. (Lots of) videos available on my Youtube channel[6], code/details available here[7][8], blog post coming soon :)

Wow. Great stuff! Is there a good way to use one a video at a very low framerate (perhaps 0.1-1 fps) with low resource requirements as animated wallpaper on Ubuntu/Linux?
Oh, hello! I enjoyed your motion interpolation experiments, and I look forward to the blog post.
Awesome work and thanks for the helpful links. Would make a really cool background / screensaver to loop the prior days imagery in HD :)
