<p>After more than seven years in orbit, the ESA Swarm satellites have provided an already large statistics of measurements of several important physical parameters of the ionosphere. In particular, electron density and temperature are measured by pairs of Langmuir Probes, and the quality of such data is now considered good enough for many studies, either science cases or climatological characterisations. Concerning specifically the electron temperature, a rather elusive parameter which is quite difficult to correctly characterize “in situ”, and for which the past literature is not so abundant with respect to other ionospheric physical quantities, the overall distributions observed by Swarm are qualitatively consistent with expectations from theory and past observations. However, a non-negligible amount of high and very high electron temperature values is regularly observed, whose distributions and properties are not trivial. In this study we aim at characterizing such features statistically as a function of latitude, local time, and season.</p>

High Electron Temperature

Abstract. We study the temperature ratio of protons and electrons based on statistics of Cluster observations in the Earth's magnetotail from 2001 to 2004. During these years, from June to November, the Cluster spacecraft visited the plasma sheet at the distance r~−19 RE. We use proton and electron moments collected in the central region of the plasma sheet (|Z|<5 RE). We find an average ratio of proton and electron temperatures ⟨Tp/Te ⟩ &amp;approx; 3.5. The dependence of Tp on Te can be approximated by the power-law function: Tp &amp;approx; 11Te0.62, where Tp and Te are measured in MK. A previous reported ratio ⟨Tp/Te ⟩ ~ 7 is limited to small electron temperatures <20 MK. The observations with the high electron temperature correspond to smaller values of the electron density and larger values of the proton and electron bulk velocities. A correlation between Te and curlometer current density is not found.
