I don't think the whole thing is 4 hours old. It takes a satellite 90 minutes to circle the earth, and I definitely see dark patches where there are gaps between orbits. I suspect it's 4 hours since the newest data.

That would explain the absence of night time.

You can see some of the full resolution images here....

http://www.satimagingcorp.com/gallery/

There are like 16 hi-res image satellites and as many med-res...

You have to download the program to scan the images though and get the fine details..

I would like to learn how they remove the water blue the atmosphere does to images from well either Space or Extremely High altitudes.

With my High altitude imagery, and live videos, the higher and higher I get, the bluer and bluer everything gets till it is almost like a B&W image but made of all shades of blue.

Pretty cool, thanks. Not as detailed as Google earth, but more up to date. Crazy there is no ice on the Great Lakes this time of year. Even Lake St. Clair (3 miles from me) is open. There was no ice fishing this year.

To get the 'full monty' you have to download the software program in a virtual machine...

Tell me about it. I am one of the few people disappointed by the weather this winter. I live in the lee of the Lake Eire - I bought a fat bike to ride the snow mobile trails this year - I'm riding the ATV trails instead, in about 4 inches of mud.

Don't tell Fredski it is getting warmer out there.

On a related note: NASA is releasing some of it's software for free.

Many thanks.

It is surprising just how much cloud is around at this time.....I hope it will clear a bit soon!!

For anyone interested in European weather, I use this link (which you might need to "trim off" the time code to get actual pictures):-

Thanks a lot for showing us. I Hadn't seen it yet...

Regarding the base layer, The Earth itself doesn't change that rapidly, so they probably use only imagery taken during the daytime for that. I suspect the cloud layer, among others, is taken at least partially using IR, so that can be continued at night.

What a change from when I used a microwave dish to receive a slow-scan image that took many seconds to download a single B/W low-res image! Was that in the early '80s?
