Scientific Highlights

The top panel shows the modeled vertical drifts at Jicamarca (red line) and the ones observed by the Jicamarca ISR (blue crosses). The bottom panel shows the the same modeled vertical drifts (red line) and the IMF Bz value (green line). Both of these panels are for the 2nd and 3rd of April 2004. The first of these days was geomagnetically quiet; a geomagnetic storm occurred on the 3rd.

The correlation with Bz suggests that the penetration of electric fields influence equatorial drift throughout the storm period. The model does a reasonable job of simulating the radar data. Click here for more information.

Spotlight Movie

This movie shows Magnetosphere and Ionosphere parameters for a solar event in May 2005. Notice the auroral activity on May 15, 2005 @ 6:00 (about 13 seconds into the video). The Ionospheric electron density in the E-region is visualized first, with a transition to the F region electron density, followed by a transition to the F-region neutral temperature.
