ASCII Listing of High Resolution Magnetic Field Data

This page provides ASCII listings of Geotail MGF high resolution magnetic field data (1/16 sec sampling) for any available intervals through interactive forms.

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. If OK, click "Submit" button.
