Plot of Magnetic Field, Electric Field, and Ion Moment Data

This page provides plots of Geotail MGF magnetic field, EFD electric field, and LEP ion moment data for any available intervals through interactive forms. Generated postscript files can be downloaded.

1. Select date and time interval.

Start Time (HHMM): End Time (HHMM):

2. Select a coordinate system.


GSM: X to the sun; X-Z plane contains the Earth's dipole axis.
GSE: X to the sun; Z along the ecliptic pole.
SM : Z along the Earth's dipole; X-Z plane contains the sun direction.
The Y axis completes the right-handed coordinate system, Y=Z x X (duskward).

3. Select an editor.

Editor-B (DSN) Editor-A (UDSC/USC)

The Geotail satellite has two editors onboard: The Editor-A data are only acquired with the real-time operation in Usuda Deep Space Center (UDSC) or Uchinoura Space Center (USC), Japan, while the Editor-B data are continuously recorded in the onboard tape recorders for 24 hours and are dumped to the NASA JPL Deep Space Network (DSN) stations.

4. You can choose the following plot options.

Coordinate System for the B and V Vectors: Cartesian Polar
Logarithmic scale: Ion Density Ion Temperature
Grid lines with major ticks: X Axis Y Axis
Paper Size for Postscript: A4 US Letter

5. If OK, click "Submit" button.
