Ground-based observations
Correlation between ground-based observations of substorm signatures and magnetotail dynamics
... The field line tracing has been done according to the empir- ical magnetic field model by Tsyganenko and Stern (1996). The input parameters for the model have been adjusted ac- cording to the solar wind and D st ...
