It's nice to see that folks are enjoying this — it was a group effort to wrestle the 22.3 gigs of imagery frames over FTP and get them cropped, processed, overlaid and sorted in time. For anyone who wants to dig deeper, the RAMMB branch of NOAA in Colorado maintains a page of GOES16 loops of the day: http://rammb.cira.colostate.edu/ramsdis/online/loop_of_the_d... ... and also runs a fancy imagery viewer where you can…

It would be really awesome to have this as wallpaper on a 4K monitor and have it update every 15 minutes. Is there a fixed URL to the most recent image?

I think that's the second link?

Is there a tendency for Hurricane eyes to 'open' at night and close again in the morning, or was it coincidence?

My hunch is that it's just an artifact from the shift in imaging technologies from visible wavelengths to infrared (or somesuch).

Wow, just wow. I didn't realize there finally are more cameras that can provide this image quality in space, beyond the one that is (was?) on the ISS. Also kudos to NYT for the way they put it together. I'm mesmerized by the globe video.

GOES-16 was just launched in November last year. https://arstechnica.com/science/2017/01/witness-the-firepowe... There are 3 more of them scheduled for the next 20 years.

Amazing comparison of Hurricane Irma from the new GOES-16 vs the old GOES-13:

The performance jump in capture time and resolution blew me away. Really exciting to see it coming on-line.

There isn't one that I'm aware of ... yet.

That said, the raw data is available through an S3-compatible service, here: https://osdc.rcc.uchicago.edu/noaa-goes16

With documentation about how to navigate and use the files here: http://edc.occ-data.org/goes16/getdata/

So it would be possible to script together something that cooks out a nice high-rez full disc image every 15 minutes.

For fun, here's one of the full disc frames we cropped in from:

https://d1ax1i5f2y3x71.cloudfront.net/items/0J2g1S1y2f2D1y0W...

Note that even though its 2712x2712 pixels, that's still way smaller than GOES16's potential resolution. The highest rez versions of this image that I've encountered go over 10,000 by 10,000...

NOAA Hurricane hunters fly WP-3 Orions. https://www.omao.noaa.gov/learn/aircraft-operations/aircraft... USAF 53rd Weather Reconniassance Squadron fly WC-130s. http://www.militaryaircrafthistorian.com/53rd_wrs.html Inside the eye can be calm, but the highest winds, wind shear, tornadoes, rainfall, and hail, are in the eye wall.

I tried to read a bit about it, but couldn't really find much in terms of--what makes these planes a lot more durable than your standard 737/747?

I wondered specifically why both planes were prop driven (seems like a jet engine would have more thrust and you wouldn't have to worry about wind forces on the props) and I found this, hopefully it helps with your question as well.

If you scroll down and look at South America, it's pretty remarkable how the clouds clearly carve out the Andes mountain range. All the swirling moisture from the southern Pacific smashes into the wall of the mountains and breaks apart, save for squirts that get through some of the valleys to the other side. I lost 10 minutes staring at all the details... really cool viz.

This is awesome. Thanks!

What would be the latency of the images?

Are there any equivalent satellites over Australia?
