Description

This file contains the 1-minute resolution dataset (“labeled_sunside_data.csv”) for Toy-Edens et al.’s Automated Classification of MESSENGER Plasma Observations via Unsupervised Transfer Learning. The 1-minute resolution file contains the rolled up 1-minute epoch, features that go into clustering and post-cleaning methods, spacecraft positions (in MSO), raw and cleaned clustering labels, and raw and cleaned transition name.

We ask that if you use any parts of the dataset that you cite Toy-Edens et al.’s Automated Classification of MESSENGER Plasma Observations via Unsupervised Transfer Learning (DOI to be created).

This work was supported by NASA grants 80NSSC19K0789 and 80NSSC22K0993.

 

The following tables detail the contents of the described files:

labeled_sunside_data.csv description

Column Name

Description

 Epoch

Epoch in datetime (YYYY-MM-DD HH:MM:SS)

 x_mso

x position of the spacecraft in MSO [km]

 y_mso

y position of the spacecraft in MSO [km]

 z_mso

z position of the spacecraft in MSO [km]

 norm_Btot

Magnitude of the total magnetic field normalized to 150nT. See paper for more information

 ratio_max_width

Ratio of the width of the most prominent ion spectra peak (in number of energy channels) to max number of energy channels. See paper for more information

 ratio_high_low

Ratio of the mean of the log intensity of high energies in the ion spectra to the mean of the log intensity of low energies in the ion spectra. See paper for more information

 high_intensity

Boolean if there is a peak with a higher minimum intensity threshold. See paper for more information

 spectra_counts

A ratio of spectra bins with non-zero counts to all possible spectra bins (i.e. way to determine if too much missing spectra data). See paper for more information

 raw_named_label

Raw cluster assigned plasma region label (allowed values: magnetosheath, magnetosphere, solar wind)

 named_label

Cleaned cluster assigned plasma region label (use these unless have a specific reason to use raw labels). See paper for more information

 raw_transition_name

Raw transition names (e.g. bow shock, magnetopause). See paper for more information

 transition_name

Cleaned transition names (e.g. bow shock, magnetopause) after removing likely transient transitions. See paper for more information
