There are tons of Earth observing satellites producing gorgeous detailed images, but I'm trying to figure out if any of them is capable of producing full-globe images of Earth on some regularly updated basis. Does anyone here know of such a beast? Are there weather monitoring satellites that do this?

Combination of Water Vapor (primarily), Infrared, and Visible images from the GOES-East geostationary satellite. These images were downloaded from the Dundee Receiving Station website today (images for July 6, 20081500 UTC)
Aqua and blue tones indicates higher levels of water vapor, while maroon tones indicate drier air. In the central Atlantic, Tropical Storm Bertha can be seen leaving a trail of clouds to the east as it pumps water vapor into the atmosphere. -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Thanks to Robert Beal of the John Hopkins Applied Physics Lab, I now have on my site a copy of the first color image of the Earth as a disk. It was made September 20, 1967 by the Department Of Defense Gravity Experiment satellite (DODGE). He worked on the mission, painting the spherical color target at the end of the boom and photographically assembling the color image. Beal sent me a file based on a print he made, which he had color balanced to resemble the ATS Earth image on my site. Upon my request he reconstructed the color scheme of the poorly imaged target from memory. I was told the colors used, similar in philosophy to Surveyor, were radiation resistant paints which happened to be of low saturation. The idea of a spherical color target is interesting, and strikes me as ingenious. If both target and background are sunlit the target can supply useful information at a wide range of lighting angles. Has this method been used in other camera carrying spacecraft?
In a separate version I have repainted the color target, fixing the motion blur in the boom in the blue channel, and tried to 'fine tune' the Autochrome like image into a kind of 'reconstruction' of how it might have appeared if all imaging steps worked ideally. http://www.donaldedavis.com/2003NEW/NEWSTUFF/DDEARTH.html Don |
