ExPRES Jovian Radio Emission Simulations Data Collection v11

Tuesday 19 December 2023, by Corentin Louis

This collection is composed of pre-computed simulation runs of the ExPRES code, with a fixed set of parameters, and for various observers, as described in Louis et al. (2019).

This data collection contains pre-computed ExPRES simulation runs, with the following input parameters:

  • Magnetic Field Model: JRM33 (Connerney et al, 2021)
  • Current Sheet Model: Connerney et al (2020)
  • CMI Mechanism: Loss Cone, with a 1° sheet thickness
  • Electron energy: 3 keV

The altitude of the Jovian aurora is set to 650 km (this constrains the maximum value of fc). There is no refraction.

The precomputed observers and associated time ranges are:

  • Earth (1990-01-01 to 2024-12-31)
  • Juno (2016-01-01 to 2023-12-31)

The data files contain the modelled following parameters: polarization, theta, CML (obs longitude), obs latitude, obs distance, srcfreqmax, srcfreqmaxCMI, srcLongitude,fp and fc (detailed informations are available in Louis et al (2019)).

The data files are provided in CDF format, and the ExPRES input files are JSON files.
