I don't know the instrument--but that sort of thing is frequently due to a double reflection within a window that separates the fore-optics from the outside universe. Depending on the material (silica, sapphire, ...) you get a significant fall-off for a double reflection, and then the same fall-off to quad, etc.

Good catch! It is indeed the Neogene-Miocene period as the last step in the animated gif. The work that Stu originally referred to was done in collaboration by Dr. Ron Blakely of Northern Arizona University. (The animations in the wikipedia entry were done by Dr. Ron Blakely.) Here is his website that has individual maps of each of the paleo-reconstructions (including Pleistocene and Present) : http://jan.ucc.nau.edu/~rcb7/mollglobe.html And a website to other detailed data products: http://cpgeosystems.com/index.html I recently got a copy of his (beautifully illustrated) book: "Ancient Landscapes of the Colorado Plateau", mentioned on his site. I highly recommend it. Yes, this is a good dataset. We've used a smoother version of this animation in Science On A Sphere. http://sos.noaa.gov/datasets/Land/paleo.html A frame exists for the future projection of the continents. I've considering making an augmented version of the animation that incorporates this into the future. Steve -------------------- Steve [ my home page and planetary maps page ]

Here's a colorization of this LRO Earth image. Below is a preview at 10% resolution, 1/2 res version is available here (2.3 MB) and full res version here (8 MB). [attachment=22521:lroc_ear...00809_th.jpg] Very lovely, except for the Photoshop masking artifacts around the edge (mainly in the 12 o'clock to 2 o'clock positions). |

The NPP mission is making a Global Image (not just hemispherical) of the Earth every day. Here is the first image release:

Rosetta Earth flyby 2 revisited, magnified 1.5x from original scale and rotated so north is up:
This one was hard to work with. The red and especially the green channel suffers from a ghost image which makes the composite look ugly. I tried subtracting them out as best as I could but it still left residual images of the bright clouds in the green channel. As a result, fair portions of the sea and cloud areas use synthetic green while most of the land masses use RGB colorm as synthetic green doesn't produce satisfactory color. -------------------- |

I abandoned the very same data set for the reasons you mention.... GREAT work.

Here is a sample image from the Himawari AHI color imager. Full color and very high resolution. The available one is 11000x11000 pixels (about 1km resolution). This is a sample of a newly launched weather satellite. Will be interesting to see how high of a resolution is publicly available in real-time.

GOES-16 has been up a while. I'm unsure if real-time data are available yet. It's one thing to get images online, though the ABI has 16 channels and judicious use of the "data" can allow construction of more visually realistic imagery. The full disk data is 0.5 to 2km resolution (depending on wavelength) every 15 minutes.
The main idea is that red is at 500m resolution, blue is at 1km, and near-IR data at 2km can be used to help synthesize the green vegetation. Most of the "True-Color" online images are actually somewhat enhanced, though access to the data can help to make more of a natural color image. The thing I would look for is the ABI L1b radiance products. Maybe CLASS will be made public in the near future? -------------------- Steve [ my home page and planetary maps page ]
