Corresponding Dataset of Advanced Water Vapor Radiometer Data for Juno Gravity Science Troposphere Calibrations README FILE Dustin Buccino August 24, 2021 Jet Propulsion Laboratory California Institute of Technology ============================================================================= INTRODUCTION ============================================================================= This dataset contains high rate data collected by the Advanced Water Vapor Radiometer (AWVR) at the Deep Space Network's Goldstone Complex in California. This dataset is provided in order to supplement the submitted article to the "Radio Science" journal Buccino, D.R., et al (2021), Performance of Earth Troposphere Calibration Measurements with the Advanced Water Vapor Radiometer for the Juno Gravity Science Investigation, Radio Science, submitted October 2021. ****************************************************************** * ANY USERS OF JUNO GRAVITY SCIENCE DATA ARE HIGHLY ENCOURAGED * * TO INSTEAD REFER TO THE OFFICIAL ARCHIVE ON THE NASA PLANETARY * * DATA SYSTEM. THIS SUPPLEMENTAL DATA SET DOES NOT CONTAIN ANY * * GRAVITY SCIENCE DATA; IT ONLY CONTAINS HIGHER RATE AWVR DATA * ****************************************************************** Additional Juno Gravity Science Data may be found at the Planetary Data System: Buccino, D. R. (2016). Juno jupiter gravity science raw data set V1.0, JUNO-J-RSS-1 JUGR-V1.0, NASA planetary data system (PDS). Retrieved from https://atmos.nmsu.edu/PDS/data/jnogrv_1001/ ============================================================================= ARCHIVE INFORMATION ============================================================================= This archive contains several data types, located within subdirectories. ROOT `- PJ03/ This directory contains all PJ-03 related data, including path delay, path delay rate, calibration values, and frequency residuals. `- PJ06/ This directory contains all PJ-06 related data, including path delay, path delay rate, and calibration values. `- PJ08/ This directory contains all PJ-08 related data, including path delay, path delay rate, and calibration values. `- ADEV/ This directory contains troposphere scintillation Allan deviations from each perijove. Files are named using the start time of the file, in YYYYMMDDHHMM format, where YYYY is the year, MM is the month, DD is the day of month, HH is the hour, and MM is the minute. `- STATS/ This directory contains the Juno perijove frequency residual statistics. Only one file is present in this directory. ============================================================================= FILE FORMAT ============================================================================= This dataset contains two separate file formats as described below. ASCII plain-text files are given with the "*.txt" extension and the comma-separated text files are given with the "*.csv" extension. TXT FILES ------------------------------------------------------------------------- The ASCII plain-text files are human-readable, space-delimited text files. Each column is defined by a header row which provides a description of each column. Additional comments may be optionally specified by starting a row with the character "#". 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. ============================================================================= FIGURE REPRODUCTION ============================================================================= This section will describe the data that are used to produce the figures in the article that describes this dataset. FIGURE 1 ------------------------------------------------------------------------- Figure 1 is a photograph and is not included in this dataset. FIGURE 2 ------------------------------------------------------------------------- Figure 2 is produced using files within the "PJ03", "PJ06", and "PJ08" directories. The first row of subfigures are produced by plotting the final three columns of "pjXX_bt_zenith.txt" as a function of time. The second row of subfigures are produced by plotting the path delay componets as a function of time from the "pjXX_pd_awvr.txt" and "pjXX_pd_tsac.txt" data files. FIGURE 3 ------------------------------------------------------------------------- Figure 3 is produced using files within the "PJ03", "PJ06", and "PJ08" directories. The first row of subfigures are produced by plotting the last column of "pjXX_freq_awvr.txt" and "pjXX_freq_tsac.txt". The second row of subfigures are produced by differencing the values. FIGURE 4 ------------------------------------------------------------------------- Figure 4 is produced using files within the "ADEV" directory. Each individual file within the "ADEV" directory contains the Allan deviation. Each Allan deviation is plotted on a log-log scale and is color-mapped to the calendar date. The file naming convention gives the calendar date of data collection, with the filenames starting with YYYYMMDD, where YYYY is 4-digit year, MM is 2-digit month, and DD is 2-digit day of month in UTC time. FIGURE 5 ------------------------------------------------------------------------- Figure 5 is produced using files within the "PJ03" directory. The frequency residual from the "pj03_resid_awvr.csv" and "pj03_resid_tsac.csv" is simply plotted as a function of time. FIGURE 6 ------------------------------------------------------------------------- Figure 6 is produced using files within the "STATS" directory. This directory contains a single file, "AWVR_stats_jul2021_v3.csv" and contains the root-mean-square of the frequency residuals from Juno perijove passes. The root-mean-square of the frequency residuals are plotted using a bar plot and the percent improvement is plotted with a scatterplot. ============================================================================= ACKNOWLEDGMENTS ============================================================================= This work was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration.
