A newer version of this visualization can be found here.
This visualization is an update to a previous visualization of NASA's Earth observing fleet of spacecraft. Also incuded in this version are a couple of commercial spacecraft as well as the International Space Station and the Hubble Space Telescope. The spacecraft ephemerides are from February 2010.
The clouds are from a simulation using the Goddard Earth Observing System Model, Verison 5 (GEOS-5). The global atmospheric simulation ran at a resolution of 7-km per grid cell and covered a period from Feb 2, 2010 through Feb 22, 2010. The results of the simulation were written out at 30 minute intervals.
This visualization was created for display on the NASA Center for Climate Simulation (NCCS) hyperwall. This is a set of tiled high definition displays consisting of 5 displays across by 3 displays down. The full resolution of all combined displays is 6840 pixels across by 2304 pixels down. This movie was rendered at this high resolution, then diced up into images to be displayed on each screen.
The large animation above is diced-up into smaller pieces that can be played on the hyperwall. Each piece is named according to a standard spreadsheet convention with a1 at the upper left and e3 at the lower right. This image illustrates this naming convention used in the diced-up frame sets below.
