Statistical analysis of Jovian decametric radio emissions occurrence drivers

The Jovian decametric (DAM) radio emissions are long-known emissions whose origin is attributed to the cyclotron maser instability, which are produced above the magnetic polar regions of Jupiter.
These emissions are anisotropically beamed, so that the emissions’ observation depends on the position of the observer. We revisit here the work by Jácome et al. (2024) who studied the statistical effect of various drivers on the detection occurrence of Jovian DAM emissions, collected since 1990 with the Routine receiver connected to the Nançay Decameter Array. We analyze here the ranking of several drivers (magnetic declination, declination, distance, elongation) based on the DAM emissions occurrence dataset for Io-DAM and non Io-DAM emissions, using statistical approaches dedicated to ranking and disentangling drivers in complex systems.
