The RAMMB slider is awesome. The public access is total.
I wish all science was like this.


I can't see you finding anything like slider anywhere else. Three satelliites in geostationary orbit giving you everything all the time.

From NASA articles
On 12 March, GOES-17 joined GOES-16 (launched in 2016) in geosynchronous orbit at 22,200 mi (35,700 km) above Earth. Himawari 8 occurred at 05:16 UTC on 7 October 2014 and reached its operational geostationary orbit in October 2014, at 140.7 degrees East.

https://journals.ametsoc.org/doi/full/10.1175/BAMS-D-17-0272.1
SLIDER provides access to every pixel from the imagers aboard the GOES-16, GOES-17, and Himawari-8 satellites in real time.

The experimental version of SLIDER was unveiled for public use in June 2017 by the Cooperative Institute for Research in the Atmosphere (CIRA) in partnership with NOAA’s Regional and Mesoscale Meteorology Branch, collocated at Colorado State University.

SLIDER provides full-resolution imagery from all spectral bands, for all sectors, from GOES-16’s and GOES-17’s Advanced Baseline Imagers (ABI) and Himawari-8’s Advanced Himawari Imager (AHI). Compared to the previous generation of GOES satellites, the data volume coming from the ABI instruments has increased dramatically. In addition to three times the number of the spectral bands and four times the spatial resolution, the increased temporal resolution means that new imagery is available every 15 min for the full disk sector, every 5 min for the contiguous U.S. sector, and every minute for each of the two mesoscale domain sectors.


If that's the preference (frequency, i.e hourly) no, i did not come across any better while I would have to verify if the entire surface is really pictured hourly. I'm not that savvy in satellite imagery hence can't tell, perhaps I have to dig a bit deeper into the matter.

Until now i was believing that they pass once per day max but things change permanently.

Thanks for pointing at it.

Great, that's the part that evaded me, that's impressing and of course that sheds a new (for me) light on the matter, will re-add it to my bookmarks of course.

Thank YOU  8)

RAMMB Slider is indeed fantastic. I might have to get a faster connection for this alone!

Here's a gif of 3 recent images of the Beaufort: before, during, and after the recent cyclone. They're not evenly spaced, but chosen for less cloud cover. I've used an overlay ("Flight Level Based Cloud Layers", opacity almost minimum) to emphasize where the clouds are.

Click.

Before-after cross-fade of middle part of the melt edge. Very substantial damage already apparent. Click.

Before-after cross-fade (improved cross-fade settings) of Eastern corner of Beaufort. Impressive damage. Click.

What strikes me most about this, and I've been noticing this phenomenon during this period of low-to-average extent changes, is how with all the loss of area/volume, the ice edge barely moves.

This is why we will, much like 2012, get a big drop in extent, whether suddenly or over some extended period as enough of that much melts out for the extent to fall.

Sept. minimum still possible, though I'm pretty strongly in the camp of my July poll response: 2nd all-time, less than 4M ASIE (Jaxa), but if *all* the weak ice goes, all bets are off.

  I agree with everything you said, and appreciate it.  I just wanted to clarify that the orbits are actually sun-synchronous. Each satellite makes 14 passes a day, taking roughly 102 minutes to complete an orbit.  The ~3,000km wide field of view allows each pass to image from roughly 68° to 5° on the far side of the pole, spanning 28°.  So above 85° is imaged every pass.
  I believe that the slider actually only incorporates two of them, SUOMI and JPSS-1, which orbit opposite each other, giving us 51 minute intervals.  SUOMI is actually beyond its planned 5 year expected lifespan, but more of these satellites are planned over the next decade.

Yes, mine is shorter. rammb eats up my broadband volume. Thanks for the links. I definitely couldn't go searching for these.


Here's my effort to make RAMMB a bit more user friendly for those who have internet struggles with the demands of the slider.  I can add more upon request (including gifs if needed and as time allows), note that the "geocolor" and "natural color" appear the most resource intensive. 

I'm providing a list of links to locations around the arctic using band I2 (my favorite), with the minimum number of frames (6), and as a still image.  My hope is that this'll be gentler on this with metered/throttled/slower connections.

These are not the maximum zoom, but can be zoomed in once more.
