This applet displays total electron content (TEC) in the ionosphere, as calculated from GPS data, using the MIDAS tomographic algorithm. It is updated continuously (with a lag of about half an hour, to allow for data acquisition and processing). See the space weather page for more information about the science behind these reconstructions. See also the simple image based version.

Requires Java Run-time Environment version 1.6, or higher.
