New results on planetary lightning
Yair, Yoav
We present the latest observations from spacecraft and ground-based instruments in search for lightning activity in the atmospheres of planets in the solar system, and put them in context of previous research. Since the comprehensive book on planetary atmospheric electricity compiled by Leblanc et al. (2008), advances in remote sensing technology …
Refinements in the data analysis of VIRTIS-M-IR Venus nightside spectra
Drossart, Pierre; Piccioni, Giuseppe; Haus, Rainer +2 more
The successful long-duration radiation measurements performed by the VIRTIS instrument aboard ESA's Venus Express spacecraft have provided an excellent collection of atmospheric and surface data that stand out due to their high temporal and spatial coverage of the planet and due to a high diversity of measurement and environmental conditions. A de…
Quasi-periodic frequency fluctuations observed during coronal radio sounding experiments 1991-2009
Pätzold, M.; Bird, M. K.; Efimov, A. I. +5 more
Coronal radio sounding experiments were carried out using the dual-frequency signals of the spacecraft Ulysses, Galileo, Mars Express, Venus Express, and Rosetta. The change in differential frequency recorded at the NASA and ESA ground stations, a quantity sensitive only to the plasma along the radio ray path from spacecraft to receiver, has been …
