The data is available in TFCat format and can be loaded and processed using the TFCat python library.
How to display the catalog
To display this catalogue on top of the Juno/Waves flux density observations, we recommend using the Autoplot software (Faden et al., 2010).
Once the software is installed and the two attached files have been downloaded
- juno-waves_flux_density.vap.zip
- tfcat_juno_catalog.jyds.zip
(also downloadable here)
and unzipped, please follow the instructions below:
- load the juno-waves-flux_density.vap file by doing "File>Open .vap file..."
- load the tfcat_juno_catalog.jyds file by doing "File>Add Plot From>Local File...", go to the "param" tab:
- in "resourceURI" change
https://maser.obspm.fr/doi/10.25935/awq6-gj80/content/data/juno_waves_lesia_tfcat_2016.json
to
https://maser.obspm.fr/doi/10.25935/awq6-gj80/content/data/juno_waves_lesia_tfcat_$Y.json
(so that the script can automatically select the right catalogue file for the chosen year) - select "mode":"bounds" and finally click on "overplot"
- load the tfcat_juno_catalog.jyds file a second time by doing "File>Add Plot From>Local File...", go to the "param" tab:
- in "resourceURI" change
https://maser.obspm.fr/doi/10.25935/awq6-gj80/content/data/juno_waves_lesia_tfcat_2016.json

(so that the script can automatically select the right catalogue file for the chosen year) - select "mode":"labels" and finally click on "overplot"
Description
The data set contains the catalogue of the Jovian radio emissions identified in the Juno/Waves observations, from 2016-04-09 to 2023-01-24, with a gap between 2021-03-04 and 2021-08-31 (which will shortly be updated in version 02.1).
The catalogue between 2016-04-09 to 2019-06-24 is the same than version 01.
The radio components were visually identified according to their time-frequency morphology, and then manually encircled by contours and labelled using a dedicated program (the SPACE Labelling Tool) that records the coordinates of the contours and the label of each emission patch.
The different labels are the following:
- QP: corresponds to Quasi-Periodics burst emission. They often form a quasi-continuum of emission at the lowest frequencies. Therefore, they are include in a single daily contour (with a variable maximum frequency limit); This label also contains trapped continuum radiation and others low-frequency bursty emissions (i.e., all emissions below the broadband-kilometric emissions which is not nLF or nKOM emissions -see below)
- nLF: narrowband Low-Frequency emission (also refered as Escaping Continuum Radiation (ECR)):
-** nLFa: narrowband emission with sporadicity in the intensity;
-** nLFb: smooth narrowband emission;
-** nLFa-bKOM or nLFb-bKOM: narrow-band emission that appears in the continuity of bkOM emission; - nKOM: narrow-band Kilometric emission;
- SRC: Juno inside the sources of the broadband-kilometric, hectometric and decametric emissions (based on Louis et al., 2019);
- cal: Data used to to estimate the flux density of the Juno/Waves HFR-Low sub-receiver;
- The satellite-induced emissions were identified by comparisons with the ExPRES simulations (ExPRES Jovian Radio Emission Simulations Data Collection). These emissions are identified by a two-letter code. The 2 first letters are Io, Ga or Eu (for Io, Ganymede or Europe) and the third one is A, B, C, or D (following the usual identification of the corresponding Jovian radio source in the northern -A,B- or southern -C,D- hemisphere, and on the west -B,D- or east -A,C- limb):
- IoA, IoB, IoC, IoD: Io-induced emissions;
- EuA, EuB, EuC, EuD: Europa-induced emissions;
- GaA, GaB, GaC, GaD: Ganymede-induced emissions.
The broadband-Kilometric (bKOM), Hectometric (HOM) and Decametric (DAM) components have not been explicitly catalogued because they are the most frequent emissions in their respective frequency range. They can be selected and studied by excluding all other components and restricting to the adequate frequency range. For example, excluding nKOM, nLF and QP in the range 1 kHz - 1 MHz (in practice 1 kHz - 140 kHz as the sensitivity of Waves is very low in the range 140 kHz - 3 MHz) allows to select the bKOM component only.
Note that the satellite-induced emissions are only catalogued for the time interval 2016-04-09 to 2019-06-24. The catalogue for these specific radio emissions will be completed in a future version of the catalogue.
The following Figure displays two typical 24-hour dynamic spectra of post-processed Juno/Waves data (see Juno/Waves estimated flux density Collection) with the catalogued emissions.
Note that between 2021-01-03 00:00 and 2021-02-15 17:00 their is an anomaly in the data (low sensitvity), and therefore there is not many emissions catalogued.
