Corresponding Dataset for "Ganymede’s Ionosphere observed              by a Dual-Frequency Radio Occultation with Juno"                             README FILE                              VERSION 2                            Dustin Buccino                             April 22, 2024                       Jet Propulsion Laboratory                  California Institute of Technology

=============================================================================VERSION 2 INFORMATION=============================================================================

   Version 2 of this dataset separates the Electron Density profile from themain data files and makes a correction to the egress profile that wasdiscovered. Differences in egress profile are very small and withinthe uncertainties. Furthermore egress is statistically a non-detection(zero densities), but for sake of accuracy they are reposted to beconsistent with the publication.

=============================================================================INTRODUCTION=============================================================================

    This dataset contains processed radio science data and results of theJuno Ganymede radio occultation. This dataset is provided in order to supplement the submitted article to the "Geophysical Research Letters"journal:

    Buccino, D.R., et al (2022), Ganymede’s Ionosphere observed by a     Dual-Frequency Radio Occultation with Juno, Geophysical Research     Letters, submitted February 2022.

    Please note the raw data used in this analysis are not provided in thissupplementary dataset. The raw Juno Gravity Science Data may be found at the Planetary Data System:

=============================================================================ARCHIVE INFORMATION=============================================================================

    This archive contains two files within the root directory.        ROOT     `- JunoG34OccData_Egress_v2.csv

            This data file contains the EGRESS data relevant to the radio            occultation. The data is a timeseries of impact parameter, sky            sky frequency at X-band and Ka-band, the dual-frequency             combination, the calibrated dual-frequency, Total Electron             Content.

     `- JunoG34_GRL_Egress_Profile_v2.csv

            This data file contains the EGRESS Electron density, and             1-sigma electron density uncertainty.

     `- JunoG34OccData_Ingress_v2.csv

            This data file contains the INGRESS data relevant to the radio            occultation. The data is a timeseries of impact parameter, sky            sky frequency at X-band and Ka-band, the dual-frequency             combination, the calibrated dual-frequency, Total Electron             Content.

     `- JunoG34_GRL_Ingress_Profile_v2.csv

            This data file contains the INGRESS Electron density, and             1-sigma electron density uncertainty.

=============================================================================FILE FORMAT=============================================================================

    This dataset contains only a comma-separated text files which aregiven with the "*.csv" extension.

    CSV FILES    -------------------------------------------------------------------------

    The Comma-Separated Value (CSV) files are plain-text files. Values in    each data file are separated using a comma ",". Each column is defined     by a header row which provides a description of each column.
