Substorm Onsets and Phases (SOPHIE), 2000-2002 with varied EPT

dataset
posted on 2024-04-23, 09:37 authored by Colin ForsythColin Forsyth, Mervyn Freeman, Christian LaoChristian Lao

Outputs from the SOPHIE (Forsyth et al., 2015, 10.1002/2015JA021343) substorm onset and phase detection technique for SuperMAG data between 2000 and 2002 (inclusive).

This version has been updated in to include the MLT and MLAT of the SuperMAG station providing the SML data and as well as the change of SML during the phase (DeltaSML) value of SML at the end of each phase (SMLatEnd)

The files provide the start times of growth/energy input, expansion and recovery phases determined by SOPHIE for the following EPTs:
2023JA031812_DS01 - EPT 05

2023JA031812_DS02 - EPT 10
2023JA031812_DS03 - EPT 15
2023JA031812_DS04 - EPT 20
2023JA031812_DS05 - EPT 25
2023JA031812_DS06 - EPT 30
2023JA031812_DS07 - EPT 35
2023JA031812_DS08 - EPT 40
2023JA031812_DS09 - EPT 45
2023JA031812_DS10 - EPT 50

2023JA031812_DS11 - EPT 55
2023JA031812_DS12 - EPT 60
2023JA031812_DS13 - EPT 65
2023JA031812_DS14 - EPT 70
2023JA031812_DS15 - EPT 75
2023JA031812_DS16 - EPT 80
2023JA031812_DS17 - EPT 85
2023JA031812_DS18 - EPT 90
2023JA031812_DS19 - EPT 95

Data generated for "On the association of substorm identification methods" by Lao et al., submitted to J. Geophys. Res.

The data is presented in 7 columns: -

The date and time of the first data point in the given phase (YYYY/MM/DD-HH:MM:SS)

The phase number (1 for growth/energy input, 2 for expansion, 3 for recovery)

A flag indicating that the rate of change of SMU is similar to that of SML in the expansion phase (0 for no flag, 1 for flag)

MLT of the active SML station at the shown time

MLAT of the active SML station at the shown time

The change in SML from the start of the phase to the end of the phase (i.e. from the time given on that line to the time given on the following line)

The value of SML at the end of the phase.
