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 the main data files and makes a correction to the egress profile that was discovered. Differences in egress profile are very small and within the uncertainties. Furthermore egress is statistically a non-detection (zero densities), but for sake of accuracy they are reposted to be consistent with the publication. ============================================================================= INTRODUCTION ============================================================================= This dataset contains processed radio science data and results of the Juno 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 this supplementary dataset. The raw Juno Gravity Science Data may be found at the Planetary Data System: Buccino, D. R. (2016).

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 are given 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. ============================================================================= ACKNOWLEDGMENTS ============================================================================= This work was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration.
