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?

For clouds this is one of the things I'm working on at NOAA in connection with the Science On a Sphere project. We do have a 30-min global IR animation (interpolated to 15-min) in real-time using a mosaic from the Aviation Weather Center that I am augmenting with Japan's MTSAT data. The actual time resolution does vary over the globe depending on which satellite(s) are covering the area.
My current goal within this effort is to produce an upgraded 15-min global animation by more directly using the various geosynchronous (and polar orbiting) satellites. This will work best with the Meteosat Second Generation data that I believe would have two satellites with the full 15-min resolution over their respective areas of coverage. Other satellites would be used with appropriate temporal interpolation. The IR mosaics exist in up to 2048x4096 resolution, though for display we sometimes reduce this by half when we wrap the animation around the sphere. -------------------- Steve [ my home page and planetary maps page ]
