Geotail 15sec solar wind magnetic field data
This directory provides annual ASCII files of 15-sec-averaged, solar-wind-only,
Geotail/MGF magnetic field data. This data set was created at GSFC/SPDF
from 3-sec MGF data as part of an effort to create 1-min field-plasma-merged
Geotail data as shifted to the Earth's bow shock nose. Despiking and the
separation of the solar wind data from the time-continuous data stream are
described at

This 15-s MGF data set is accessible with graphical display and parameter
and time subsetting capabilities through the FTPBrowser interface at
https://omniweb.gsfc.nasa.gov/ftpbrowser/geotail_mag15s.html
