Re-analysis of the Cassini RPWS/LP data in Titan's ionosphere. Part II: statistics on 57 flybys.

Abstract

 Three main cold electron populations are detected by the Cassini Langmuir probe in Titan's ionosphere below 1200 km altitude. One population is attributed to background thermal electrons and one to electrons linked to the photo-induced ion chemistry. A third electron population, observed on dayside below 1200 km, could be photo-or thermo-emitted from dust grains.

Re‐Analysis of the Cassini RPWS/LP Data in Titan's Ionosphere: 1. Detection of Several Electron Populations

“…In a first paper (this one), we detail the method used for the re‐analysis of the data and the detection of several electron populations. A second paper (Chatain et al., 2021), referred as “paper II,” presents the results obtained for 57 flybys and discusses the origins of the detected electron populations.…”
