Earth and atmospheric sciences

Analysis of GPS navigation signals monitored at over 120 sites provides a snapshot of ionoshperic total electron content (TEC) over North America during a major geomagnetic disturbance. A large-scale plume of storm enhanced density spans the continent from a source region in the eastern U.S. The bold red outlines the low-altitude footprint of the TEC plume.

Research scientist Chris E. Forest (seated), Professor Peter H. Stone and research scientist Andrei P. Sokolov (right) gather around a monitor displaying their climate model, which reduces the uncertainty of global climate change predictions. On the screen is a temperature record for the global mean surface temperature from 1900 to 1998.
