Ionosphere Total Electron Content - April 2001 (2005)

Synopsis

A view of the ionospheric Total Electron Content (TEC) measured over North America during a storm in April 2001. Red is high electron counts, blue is low, gray where there is no data. From the pre-storm state, we see relatively low electron counts. As the storm intensity increases, so do the number of electrons. The increase will generate more interference for communications systems, GPS, etc. Note: Closeup view of TEC data over North America, with dates. Animator: Tom Bridgman (GST). Scientist: Anthea J. Coster (MIT/Haystack), John Foster (MIT/Haystack), Robert Robinson (NSF), Marlene Colerico (MIT/Haystack). Platforms/Sensors/Data Sets: NAVSTAR/World-wide GPS Receiver Network.
